Many large industrial furnaces are designed to capture and recycle process heat via stoves, regenerators or recuperators. In these instances 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. Hotwork is often used for the initial furnace heatup with these silica materials in order to ensure uniform heating and therefore uniform expansion. Whether it is a coke oven or a glass furnace, Hotwork has years of experience providing the initial heat up of these expansion critical materials.
