Silicon carbide rammed bodies are suitable for lining the combustion zones of high-pressure cyclone burners of steam boilers. The life of the silicon carbide body depends on the heat resistance of the supporting joints (the hooks). The life of such a body in cyclone burners is 4–5 times longer than chromite rammed bodies PKhM-6. The life of silicon carbide bricks used to line the cyclone

Process Burners 101 - AIChE

Refractory is used on all steam-generating boilers. Its primary function is to close and seal all openings or gaps so that the fire, heat, gas, and fly ash will not escape the confines of the boiler. Regardless of boiler type, refractory applications are similar, such as refractory-filled wall boxes, refractory on tube walls in non-membrane areas, and at least one large refractory seal somewhere inside the boiler.

Boiler types - Marine Engineering - Beyond Discovery

Determining the hot face refractory maximum use temperature is not an exact science. Refractory datasheets may list a maximum use temperature but these values are based on an oxidizing environment and no applied load. In a Thermal Reactor the burner is operated in a reducing environment and the refractory is under varying compressive load.
