New hires progress through multiple stages of training before taking on full responsibilities in the field. Each stage is designed to reinforce safe work practices and operational knowledge. ![furnace heatup technician training session](https://hotwork.com/wp-content/uploads/2026/03/pic-furnace-heatup-21.jpg "pic-furnace-heatup-2(1) | Spie Hotwork | Spie Hotwork") ![refractory dryout technician field training](https://hotwork.com/wp-content/uploads/2026/03/pic-refractory-installers-31.jpg "pic-refractory-installers-3(1) | Spie Hotwork | Spie Hotwork") ![SPIE Hotwork Logo](https://hotwork.com/wp-content/uploads/2026/02/SPIE_RGB_BLAU_HOTWORK.png "SPIE Hotwork Logo | Spie Hotwork | Spie Hotwork") ## Why Training Is Critical in Refractory Dryout and Furnace Heatup Operations Refractory dryout and furnace heatup work occur in environments where precision and safety are essential. Industrial furnaces, boilers, kilns, and processing units rely on refractory linings that must be heated carefully and gradually during startup. If refractory materials are heated improperly or too quickly, moisture trapped inside the lining can expand rapidly, potentially causing cracking, spalling, or structural damage. Because of this, the work performed by refractory dryout and heatup technicians directly impacts the long-term reliability of industrial equipment. SPIE Hotwork technicians are trained to understand the technical and safety requirements associated with: - Controlled combustion heating - Engineered heat curves - Industrial furnace startup procedures - Safe burner ignition and monitoring - Industrial hazard recognition This knowledge ensures that projects are executed safely while protecting critical industrial infrastructure.

The lining could be constructed from bricks or from pre-fired cast shapes. Unlike [**refractory dryouts**](/services-technology/refractory-dryout/), the mechanical properties of the refractory lining are not created during this initial heating in the field – they were created when the bricks or shapes were fired at the factory. Many large industrial furnaces are designed to capture and recycle process heat via stoves, regenerators or recuperators. In these instances SPIE Hotwork is often used to provide the initial heat up so that the process has the energy to sustain itself. Some facilities are constructed out of expansion critical materials such as silica brick.

Blast furnaces, coke plants, and reheat furnaces all depend on refractory linings designed to protect structural components from intense heat and continuous thermal cycling. Before these systems can safely begin production or return to service after maintenance, their refractory linings must undergo a carefully controlled heating process. SPIE Hotwork is recognized worldwide as refractory dryout and heatup experts, providing specialized services for steel manufacturers during construction, maintenance outages, and equipment commissioning. Our technicians work alongside steel plant engineers, refractory installers, and operations teams to perform controlled furnace heatup procedures that protect refractory materials and support safe startup of steel production equipment. With decades of experience supporting **[industrial furnace heatup projects](/industry-solutions/)**, SPIE Hotwork has developed extensive knowledge of the unique operating conditions found in steel manufacturing facilities.

During construction or maintenance outages, refractory materials may absorb moisture from the surrounding environment or installation materials. If heat is applied too quickly during startup, trapped moisture may expand rapidly and cause serious damage. Potential risks include: - Cracking within refractory linings - Spalling of refractory surfaces - Structural damage to furnace systems - Delayed production startup Controlled refractory dryout allows moisture to escape gradually before the furnace reaches operating temperatures. [**SPIE Hotwork technicians**](/about-hotwork/experience/) apply heat using engineered heat curves and specialized combustion equipment. This controlled heating process protects refractory materials and supports reliable furnace performance during startup. Proper heatup procedures help extend the life of refractory linings and maintain safe operating conditions within steel manufacturing facilities. ![](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Steel-Industry-Blast-Furnace.jpg "Hotwork-Steel-Industry-Blast-Furnace | Spie Hotwork | Spie Hotwork") ## Steel Industry Equipment Supported by SPIE Hotwork Steel plants contain multiple types of refractory-lined equipment used throughout the steel production process. SPIE Hotwork provides refractory dryout and furnace heatup services for systems including: - Blast furnaces - Byproduct coke plants - Direct reduced iron units - Heat recovery coke plants - Induction coating pots - Reheat furnaces Each of these systems requires specialized heating procedures to ensure refractory materials reach operating temperatures safely. SPIE Hotwork technicians coordinate closely with plant personnel to ensure heatup procedures align with operational schedules and commissioning requirements. ![Blast Furnace Solutions](https://hotwork.com/wp-content/uploads/2026/03/BLAST-FURNACE-SOLUTIONS.jpg "Blast Furnace Solutions | Spie Hotwork | Spie Hotwork") ![SPIE Hotwork Logo](https://hotwork.com/wp-content/uploads/2026/02/SPIE_RGB_BLAU_HOTWORK.png "SPIE Hotwork Logo | Spie Hotwork | Spie Hotwork") ## Blast Furnace Heatup Operations Blast furnaces are among the most important systems within steel manufacturing facilities. These furnaces are used to produce molten iron, which is later converted into steel. Blast furnaces operate continuously and rely on refractory linings designed to withstand extreme thermal conditions. During commissioning or after major maintenance work, blast furnace refractory linings must be heated gradually to prevent structural damage. SPIE Hotwork provides controlled furnace heatup services that allow blast furnace refractory systems to reach operating temperatures safely. Our technicians monitor heating conditions carefully to ensure temperature increases follow engineered heat curves designed to protect refractory materials.

Refineries and petrochemical plants rely on refractory-lined furnaces, heaters, and processing units designed to withstand extreme temperatures and demanding operating conditions. Before these systems can safely enter operation or return to service after maintenance, the refractory lining must undergo a carefully controlled heating process. This process removes moisture from the refractory material and prepares the system for safe startup.

During installation or maintenance outages, refractory materials can absorb moisture from the surrounding environment or from installation materials. If heating occurs too rapidly during startup, this trapped moisture may expand quickly, potentially causing: - Cracking within the refractory lining - Spalling of refractory surfaces - Structural damage to furnace components - Delays in commissioning or plant startup Controlled refractory dryout allows this moisture to escape gradually before the equipment reaches operating temperatures. SPIE Hotwork technicians use specialized combustion equipment and engineered heat curves to apply heat in a controlled and evenly distributed manner. This approach protects refractory materials while preparing processing units for safe operation. Proper refractory heatup procedures help ensure reliable long-term operation of hydrocarbon processing equipment. ![FCCU refractory dryout procedure](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Hydrocarbon-img3.jpg "Hotwork-Hydrocarbon-img3 | Spie Hotwork | Spie Hotwork") ![industrial technician monitoring refinery furnace heat curve](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Hydrocarbon-img4-1024x682.jpg "Hotwork-Hydrocarbon-img4 | Spie Hotwork | Spie Hotwork") ![SPIE Hotwork Logo](https://hotwork.com/wp-content/uploads/2026/02/SPIE_RGB_BLAU_HOTWORK.png "SPIE Hotwork Logo | Spie Hotwork | Spie Hotwork") ## Hydrocarbon Processing Units Supported by SPIE Hotwork Hydrocarbon facilities contain multiple types of high-temperature processing units that require specialized heatup procedures.

These furnaces contain refractory linings designed to withstand extreme heat while maintaining structural stability throughout the glass production process. Before a glass furnace can begin operation or return to service after maintenance, the refractory lining must undergo a carefully controlled heating process. This process removes moisture from the refractory material and prepares the furnace for safe operation. SPIE Hotwork is recognized worldwide as [**refractory dryout and heatup experts**](/industry-solutions/), providing specialized services for glass furnace startup and commissioning. Our technicians work alongside glass manufacturers, engineering teams, and refractory installers to perform controlled furnace heatups that protect refractory linings and support reliable plant operations. SPIE Hotwork first began providing combustion heatup services to the glass industry in the mid-1960s. Since then, our team has supported glass furnace startups and maintenance operations at facilities around the world.

The refractory materials inside these furnaces must be heated gradually during startup to prevent structural damage. During installation or maintenance outages, refractory materials can absorb moisture from the surrounding environment. If the furnace is heated too quickly, this trapped moisture may expand rapidly and cause cracking or spalling. Controlled furnace heatup allows moisture to escape safely while gradually bringing the furnace to operating temperature. SPIE Hotwork provides specialized combustion equipment and trained technicians to perform this process according to engineered heat curves designed to protect refractory materials. Proper heatup procedures help ensure the long-term reliability and performance of glass furnaces. ![industrial furnace heatup technician working in glass plant](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Glass-Furnace-Heatup-Services-Brickwork-Crown-1.webp "industrial furnace heatup technician working in glass plant | Spie Hotwork | Spie Hotwork") ![portable combustion equipment for glass furnace heatup](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Glass-Cullet-Filling-Services-1024x682-1-1.jpg "portable combustion equipment for glass furnace heatup | Spie Hotwork | Spie Hotwork") ![SPIE Hotwork Logo](https://hotwork.com/wp-content/uploads/2026/02/SPIE_RGB_BLAU_HOTWORK.png "SPIE Hotwork Logo | Spie Hotwork | Spie Hotwork") ## Glass Industry Services Provided by SPIE Hotwork SPIE Hotwork supports glass manufacturers with a range of specialized services designed to assist with furnace startup, maintenance, and operational transitions.

SPIE Hotwork has the ability to blow cullet into the furnace using a cullet gun. This method has the advantage of distributing the cullet deep into the furnace to allow for rapid melting. It avoids placing a large cold mass of cullet in the doghouse which has been known to cause [**refractory problems**](/industry-solutions/refractory-installers/). Some clients are concerned about dusting of the furnace superstructure that may occur when blowing dry cullet. This problem is of more concern to some clients due to the specific quality of the cullet that they use, the type of refractories utilized in the furnace, the quality of the glass that they produce and other factors. In order to address this issue, SPIE Hotwork has introduced multiple solutions. The first solution is a cullet wetting system which minimizes the dusting condition by wetting the cullet with water before blowing it into the furnace. SPIE Hotwork’s second solution is screening the cullet prior to blowing it into the furnace (either on the cullet pad or in-line with the cullet gun). Screening allows for removal of fine particles which become airborne during the blowing process. Each of these solutions allows the benefits of blowing cullet (wide distribution, fast melting rates) while minimizing the dusting condition. For those most concerned about the potential for dust from blowing cullet, **[SPIE Hotwork](https://maps.app.goo.gl/vxHnhgAahRrfvQCo6)** also has introduced a vibratory cullet feeder.

The package boiler generates steam which is used to heat the process solutions via a heat exchanger. The solutions are then pumped up to and through the boiler tubes and the solution loses temperature throughout the piping loop. SPIE Hotwork can provide an alternative to the lead time, installation expense and transportation of large package boilers and heat exchangers for this function. SPIE Hotwork’s portable burner system can be used to fire into the firebox and provide the temporary heat source for heating the [**chemical cleaning solutions**](/industry-solutions/other-industries/chemical-processing/). This method has the advantage of controlling the process temperature where the reactions are taking place (in the tubes) versus doing it remotely. After all, the boiler tubes are designed to be heat exchangers. [**SPIE Hotwork**](https://maps.app.goo.gl/vxHnhgAahRrfvQCo6) has also provided temporary heat solutions for freeze protection during construction and commissioning in cold climates. Once the tubes have been initially charged with fluid, they remain vulnerable to damage from freezing until they are finally placed into continuous service. SPIE Hotwork can provide freeze protection heating in order to avoid repeatedly draining and purging the system during commissioning activities. SPIE Hotwork can also provide temporary heat for steam blows, pressure tests and other commissioning activities prior to initialization of the main boiler combustion system.

These systems rely on refractory linings designed to protect structural components from extreme temperatures and continuous thermal cycling. Before a boiler system can safely begin operation, its refractory lining must undergo a carefully controlled heating process. This process removes moisture trapped within the refractory material and ensures the lining reaches operating temperatures without structural damage. SPIE Hotwork is recognized worldwide as [**refractory dryout and heatup experts**](/industry-solutions/), providing specialized services to boiler operators, power generation facilities, and industrial plants that depend on reliable boiler performance. With decades of experience supporting industrial startup and commissioning projects, SPIE Hotwork technicians work alongside plant operators, refractory installers, and engineering teams to perform safe and controlled refractory dryout and furnace heatup operations.

The refractory materials used inside these systems must withstand intense heat, pressure, and chemical exposure. During construction or maintenance outages, refractory linings may absorb moisture from the surrounding environment or installation materials. If a boiler is heated too quickly, that moisture can expand rapidly, potentially causing cracking, spalling, or structural damage. Controlled refractory dryout is required to remove this moisture gradually and safely. SPIE Hotwork provides the expertise and specialized combustion equipment required to heat refractory linings according to engineered heat curves. This controlled process protects the refractory lining and helps ensure the long-term reliability of the boiler system. ![HRSG boiler refractory heatup process](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Other-Boiler-Services-1024x682-1.jpg "HRSG boiler refractory heatup process | Spie Hotwork | Spie Hotwork") ![industrial technician monitoring boiler startup heat curve](https://hotwork.com/wp-content/uploads/2026/04/67_0-765x1024-1.jpg "industrial technician monitoring boiler startup heat curve | Spie Hotwork | Spie Hotwork") ![SPIE Hotwork Logo](https://hotwork.com/wp-content/uploads/2026/02/SPIE_RGB_BLAU_HOTWORK.png "SPIE Hotwork Logo | Spie Hotwork | Spie Hotwork") ## Boiler Systems Supported by SPIE Hotwork SPIE Hotwork provides refractory dryout and furnace heatup services for a wide range of industrial boiler systems used in power generation and heavy industrial processes.

Mr. Ward had invented a special [gas burner](/services-technology/hotwork-equipment/), and he formed the company to capitalize on his invention. Initially the burner design was patented, and the company grew rapidly due to the utility of its invention for glass furnace heatups. In order to support the growth of his company, Mr. Ward formed subsidiaries and granted licenses under his patents. A network of subsidiaries and independent companies began to operate around the world utilizing the original intellectual property. In 1965, Hotwork Incorporated was formed as a licensee of Mr. Ward’s company for North and South America. The US company has prospered and continued to develop and expand the original technology transferred from Mr. Ward through the stewardship of different owners along the way. Over time, Mr. Ward’s company grew rapidly, expanded product lines, and then fell onto hard times. In the 1990’s, it became insolvent, divested product lines, and a remnant English entity (Hotwork Europe LTD) was eventually purchased and shut down by Hotwork. Hotwork also acquired Hotwork Australia. Over the decades, Hotwork in the USA continued to improve the technology, expand the service offerings to include refractory dry outs, and grow geographically. In 2005, Hotwork was separated from a larger corporate owner and became a private company known as Hotwork – USA LLC. In 2024, Hotwork – USA was acquired by SPIE and continues to offer the same high-quality services with the same innovative approach that had been so successful over the 60 years of operation. Today, there are still several companies operating around the world utilizing Hotwork in their name in some form. Most of them have their roots in an association with Mr. Ward’s original company. Some of them have absolutely no association with SPIE Hotwork. Today you can recognize [SPIE Hotwork](https://maps.app.goo.gl/vxHnhgAahRrfvQCo6) by the trademark (Hotwork®), the web address www.hotwork.com , and by the Lexington, KY USA headquarters. 1965 – Hotwork Incorporated opens in Hillside, NJ. 1975 – Hotwork Inc. moves to current headquarters in Lexington, KY. 1990 – Hotwork Inc. becomes Hotwork Division of Adience, Inc. 1992 – Adience divests the Hotwork Division, and it becomes privately held Hotwork Corporation. 1998 – Hotwork Corporation becomes Hotwork Division of Fosbel, Inc. 2005 – Fosbel divests Hotwork Division and it becomes privately held Hotwork – USA LLC. 2022 – Robur Group acquires Hotwork – USA LLC. 2024- SPIE acquires Robur Group and Hotwork – USA LLC.

Unlike many contractor-based industrial jobs, we invest heavily in technician development. ### Two Weeks of In-House Technical Training Every new technician completes two weeks of structured instruction before entering the field. This includes: - Combustion system fundamentals - Refractory material behavior - Moisture control and heat curves - Equipment handling - Safety compliance protocols This ensures that new hires understand not only what to do — but why it matters. ### 60–90 Days of Field Training Following classroom instruction, new technicians work directly alongside experienced supervisors on active projects. This field-based training allows real-time learning under professional oversight. Hands-on exposure builds confidence and technical skill before independent responsibility. ### 40–50 Hours of Annual Continuing Education Every year, technicians complete ongoing training to maintain compliance standards and technical excellence. This includes: - Safety updates - Equipment improvements - Industry best practices - Compliance requirements ### Annual MSHA Certification Many industrial projects require MSHA training. SPIE Hotwork maintains annual MSHA credentials for team members involved in regulated environments.

In order to achieve the desired refractory properties, the material needs to be thermally treated to remove the water used in casting and to achieve the ceramic bonds inside the lining. The process of converting the as-installed refractory material into the final lining with the specified physical properties is the refractory dryout. The properties of the final lining are achieved by the culmination of manufacturing controls in the manufacture of the refractory material, adherence to mixing and placement practices specified by the manufacturer, and finally, a proper thermal cycle to drive off the water and complete the chemical reactions. ![Refractory Dryout](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Refractory-Dryout-1-1024x682-1.jpg "Hotwork-Refractory-Dryout-1-1024x682 | Spie Hotwork | Spie Hotwork") **[SPIE Hotwork](https://maps.app.goo.gl/vxHnhgAahRrfvQCo6)** has a proprietary burner that is specifically designed for the task of drying refractories. Generally, drying refractory means executing a thermal cycle that starts at ambient temperatures and follows a curve specified by the manufacturer. In addition to the gradual temperature ramp, it is important to pressurize the vessel in order to obtain temperature uniformity and to provide adequate changes in the atmosphere to carry away the moisture that is being evolved from the lining. The SPIE Hotwork excess air burner is uniquely suited to provide a controlled refractory dryout from ambient temperature throughout the specified dryout curve. Furnace process burners are designed to heat huge process burdens (**[steel](/industry-solutions/steel/), [aluminum](/industry-solutions/nonferrous-metals/alumina-and-aluminum/), [cement](/industry-solutions/cement/), etc**) and they are designed to do so at maximum energy efficiency. These burners are generally not well suited to operating at low firing rates in order to accomplish the critical low temperature portion of the refractory dryout. In addition, they are typically “ratio burners” that can only turndown about 3 to 1 and, even at minimum fire, have high flame temperatures at the burner discharge nozzle. When they are turned down, the combustion air is also decreased resulting in lower gas volume in the vessel. The SPIE Hotwork burner uses full combustion air even at the lowest temperature. This pressurizes the vessel and carries away the evolving moisture. The SPIE Hotwork burner produces a low temperature gas stream when the burner is turned down so there is no chance of localized overheating at the burner discharge. The SPIE Hotwork burner also has the capability of turning down by a ratio of 25 to 1 or more. After investing time and money to procure and install a high quality monolithic lining, why take the risk of failure during dryout or of a compromised lining life? A professional refractory dryout can help to ensure that you achieve the results you desire. --- ### [Fired Heaters, Furnaces and Reformers](https://hotwork.com/industry-solutions/hydrocarbon/fired-heaters-furnaces-and-reformers/) **Published:** March 12, 2026 **Author:** mikamo_adrian **Content:** # Fired Heaters, Furnaces and Reformers ![Coke Calcining](https://hotwork.com/wp-content/uploads/2026/03/Hotwork-Coke-Carbon-Calcining-1024x682-1.jpg "Coke Calcining | Spie Hotwork | Spie Hotwork") Fired heaters come in all sizes and configurations from small cylindrical heaters (can heaters) to large cabin heaters (or box heaters), like coke furnaces, and crude heaters. Most of these heaters have refractory linings in the radiant sections (floor), convection sections, SCR, air pre-heaters/ducts, and the stacks. The insulating castables in these sections contain large quantities of free water that can be removed with a low temperature dryout to about 800F (425C). These low temperature dryouts have been an effective countermeasure to combat the [**alkalai hydrolysis**](https://hotwork.com/resources/glossary#alkali-hydrolysis) problems that have been experienced in the industry. --- ### [Experience](https://hotwork.com/about-hotwork/experience/) **Published:** March 13, 2026 **Author:** mikamo_adrian **Content:** # SPIE Hotwork's Experience For over 60 years, **[SPIE Hotwork ](https://maps.app.goo.gl/vxHnhgAahRrfvQCo6)** has been providing **[heatup and dryout services](/industry-solutions/)** to all major refractory consuming industries.

Since then, SPIE Hotwork has helped to commission new calciners all over the world. Modern fluid bed calciners are a complex **[refractory dryout](/services-technology/refractory-dryout/)** challenge with tons of castable refractory in multiple vessels and ducts, often with limited access points for burner deployment. SPIE Hotwork has refined and improved the practices necessary to successfully dryout these complex structures. Aluminum melting and holding furnaces are typically lined with very thick, multilayer castable refractories. Because these materials contain large volumes of water, explosive spalling can occur if the lining is not properly dried out before being placed into service. The SPIE Hotwork burner system was designed and developed specifically for this type of challenge.

In refractory, bulk density can be reduced by excess porosity. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Burnout Fibers Refractory manufacturers often create intentional porosity and permeability in their materials by including fibers in the mix that will burn out (and leave voids) at low temperatures. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Burner Turndown Capability This is the ratio of the maximum firing rate of a burner divided by its minimum firing rate. Many pre-mix process burners have a turndown capability of 3 to 1. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Castable Refractories A mixture of heat-resistant aggregate materials and heat-resistant hydraulic cement. It is typically mixed with water in order to be placed by casting, ramming or gunning. Castable refractories can be installed in the field to conform to the shape of the furnace, vessel, trough, cyclone or duct.

This technology has environmental advantages and flexibility on the quality of the fuel. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Checker Burnout A term used by some to refer to the sulfate burnout process for opening clogged regenerators on a glass furnace. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Chemical Cleaning A commissioning process used in the start up of new boilers. Various cleaning and passivating fluids are temperature controlled and circulated thru the boiler tubes in order to clean and condition them before being placed into service. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Coating Cure](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) Various coatings are used in industrial processes to reduce corrosion attack and/or to change the emissivity of a surface. Frequently these coatings are applied wet and need to be dried and cured before being placed into service. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Cold Crushing Strength (CCS) This is a quality measure of a refractory that measures its resistance to compressive forces. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Cold Water Glass Furnace Drain (CWD) At the end of a glass furnace campaign, the liquid glass in the furnace must be removed in order to enable repairs to the refractory. One method for removing the liquid glass is to drill a hole in the furnace and drain the hot glass into a water stream that will quench it and transport it to a storage area. In a cold water drain, the water is used in a “once thru” manner. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Crown Rise Monitor (CRM)](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) When heating up a glass furnace, the refractory expands and the steel restraining structure must be adjusted to accommodate the expansion. In order to monitor and control this process, it is beneficial to measure the position of the refractory crown on the furnace. Traditionally this has been done by manually measuring “tell-tales” that compare the crown position to its original elevation. Crown Rise Monitor (CRM) uses linear position transducers and a data recorder to continuously monitor the position of the crown. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Cullet Broken fragments of glass collected either as a byproduct of glass manufacture or as a result of post consumer recycling. This material is frequently used as a raw material in glass manufacturing. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Cullet Filling When a glass furnace is first put into production, it is heated and must have an initial charge of glass to begin the production process. Cullet filling is often used to provide this initial charge. Cullet is frequently charged into the hot furnace either by blowing or vibrating it into the melter. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Excess Air Burner](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) This style of burner does not try to maintain a fixed ratio of fuel to combustion air. It has the advantage of providing a high volume and low temperature stream of gas at the burner discharge nozzle when turned down to low firing rates. This functionality is particularly well suited to refractory dryout. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Expansion Control Supervision (ECS) During the heatup of a glass furnace, the refractory is contained by a steel structure and large adjustment bolts. As the furnace heats up and expands, the steel structure must be adjusted to accommodate the growth of the refractory. Expansion Control Supervision is a service provided to manage these adjustments. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Freeze Protection On occasion, critical assets must be protected from freezing due to environmental conditions. Usually these issues arise either during construction or during an extended outage. Freeze protection is a service that can be used to protect critical assets during cold weather. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Furnace Heatup](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) Many industrial furnaces recycle waste heat and they rely on that recycled heat to sustain the process. Stoves, regenerators, checkers, and recuperators are all examples of technologies used to recycle process heat. When one of these process is completely cold (either due to an outage or new construction), it is often necessary to “kick-start” the process with an external heat source. Furnace heatup is a service to bring these industrial furnaces from ambient temperature up to a sustainable operating condition. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Furnace Hold Hot When an industrial furnace interrupts the generation of the process heat but it isn’t desirable to allow the process to cool down, a furnace hold hot service is often used. Emergency hold hot service is sometimes used due to utility interruptions or natural disasters. Planned hold hot services may be used when a portion of the process needs to undergo repairs and it is undesirable to cool down the entire process. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Furnace Outage Many large industrial furnaces operate 24 hours per day and 7 days per week. The processes are continuous and are rarely interrupted. On occasion, a furnace outage is scheduled in order to conduct maintenance and repairs that can only occur during a process stop. In some industries, the outages are referred to as a turnaround. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Gunned Refractories](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) Refractory material may be installed via a method known as gunning. Refractory material is transported in a compressed air stream and is projected onto the refractory surface. The material may have water added at the nozzle or may be pre-moistened. The objective is to have the material stick to the target surface and to avoid rebound. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Heat Recovery Steam Generator (HRSG) This is a type of boiler that captures excess process heat. They may be installed before the exhaust stack on an industrial furnace or they can be used in conjunction with a combined cycle power generator. A combined cycle turbine has one stage driven by the products of combustion and a second stage driven by steam from the HRSG that captures some of the heat left over after the first stage. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Hydrocarbon Processing Industries (HPI) This industry category refers to oil refining, gas processing, LNG, and petrochemical industries.

One method of removing these materials is to melt them back into a liquid and allow the liquid to flow to the desired location. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Modulus of Rupture (MOR) A quality measure of a refractory that measures its strength in resisting flexural (bending) forces. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Monolithic Refractory A refractory that is applied on-site in the unfired state and forms a continuous mass. Examples of monolithic refractory include castable, shotcrete, gunning mixes, plastic and ramming materials. Once placed, a refractory dryout is required to create the refractory properties. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Permeability ](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) The ability of a gas to pass thru a refractory structure. Permeability is enhanced when porosity interconnects and provides a gas path. Porosity does not necessarily create permeability. During refractory dryout, steam uses permeability to escape from the refractory structure. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Porosity Voids in the refractory structure create porosity. Porosity can occur as large individual voids or as micro voids dispersed throughout the structure. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Plastic Refractory A refractory mixture utilizing bonding agents such as clays, phosphates or resins. The material is typically delivered for installation as wet blocks. During installation, plastics do not require as much compaction/deformation as ramming material. The blocks are typically tamped together to form a continuous lining. Once placed, a dryout is required to create the refractory properties. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Post Weld Heat Treating (PWHT) ](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) When metal structures are welded, the heat affected zone has modified metallurgical properties compared to the parent metal. In order to restore metallurgical properties, a thermal cycle is often required. Most post weld heat treating is conducted locally on the weld with electrical resistance heating. In some cases, it is beneficial to heat an entire tank or weldament and, in these cases, combustion post weld heat treating is often deployed. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Ramming Refractory A refractory mixture utilizing bonding agents such as clay, organics, phosphates, silica or tar. The material may be delivered for installation either in wet or dry form. The material is typically compacted with a pneumatic hammer or other compacting tool. Shear created during ramming contributes to the materials density and final properties. Once placed, a dryout is required to create the refractory properties. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Ratio Burner Ratio burners attempt to maintain an optimal mixture of air and fuel. This ratio is usually slightly greater than the stoichiometric ratio in order to ensure complete combustion of all fuel. This type of burner is typically selected for process burner applications since it has good energy efficiency, environmental advantages, and is well suited to maintaining high temperature processes. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Recycled Hot Water Glass Furnace Drain (RHWD)](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) This service is similar to the cold water glass furnace drain except that the water is collected after separation from the cullet and it is recycled back to be used again in a continuous closed loop. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Refractory Cure This is the initial period after placement of a castable refractory before the start of the dryout. During this period, reactions are occurring that result in the hard set of the refractory. Typically the refractory manufacturer specifies the duration of the cure period and it may be a function of the ambient temperature. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Refractory Dryout For monolithic refractory, following installation and the cure period, heat is applied per the manufacturer’s schedule in order to drive off both free and chemically combined water. This thermal treatment is the last step in achieving the desired properties in the installed refractory. This process is sometimes referred to as bake-out, heat cure, dry out, dry-out, or preheat. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Turnaround In oil refineries and other process industries, periodic maintenance outages are planned where the process is completely stopped. Extensive planning and preparation is done to optimize the work accomplished and to minimize the downtime. These outages are frequently called turnarounds. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Regenerator Decongestion This is another term for the sulfate burnout process. ![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")### Shotcrete A refractory material that is mixed (like a castable) and then applied by pumping the mixture to a nozzle where it is mixed with air and an activator to begin the curing. The mixture is pneumatically “shot” on to the installation surface. Once placed, a dryout is required to create the refractory properties. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Ceramic Bond ](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) The mechanical strength in refractory that is developed during heat treatment and is the result of cohesion between adjacent aggregate particles. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Refractory Spall ](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) A mechanical failure of a refractory lining resulting in cracks, fractures, delamination, crumbling and/or explosive failure. Refractory spalling can occur due to many different root causes but, if it occurs, it typically happens during the refractory dryout. During dryout the refractory lining is exposed to high forces as water is converted to steam and it tries to escape the lining. If the refractory properties have been compromised due to any prior activities, then failure is likely to occur during the dryout. Refractory spalling typically occurs because the material does not have the strength to withstand the forces caused by the evolving steam during dryout. The two main issues are the material properties and the rate of steam generation. This condition is also referred to as explosive spalling or refractory blowout. Quality control procedures and adherence to the manufacturer’s mixing, placing, curing and drying instructions are the best preventative measures to avoid this condition. [![Hydrocarbon processing plants](https://hotwork.com/wp-content/uploads/2026/03/industry-2-1-1.png "industry-2-1 | Spie Hotwork | Spie Hotwork")](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/)### [Sulfate Burnouts (SBO)](https://www.hotwork.com/industry-solutions/boilers/cfb-boilers/) In glass furnaces with regenerators, sulfates tend to condense in the checker-pack over time. The accumulation of sulfates restricts air passage and eventually furnace operation is impacted. One method of removing sulfates from the checkers involves installing a burner in the bottom of the regenerator and heating the checker pack to above the melting point of the sulfates. This allows the sulfates to run out of the checkers to the bottom of the regenerator and air flow is restored to the furnace. This process is also referred to as regenerator decongestion or checker burnouts. --- ### [Employees](https://hotwork.com/employees/) **Published:** March 13, 2026 **Author:** mikamo_adrian **Content:** # Employees Material posted in the section of the website is for the personal use of authorized users only.
