Boiler refractory dry out procedure - Boilersinfo

Boiler Refractory dry out is to ensure proper drying, curing of refractory applied on furnace and other components. The refractory usually undergoes considerable chemical changes, during initial heating. Controlled heating, through these reactions ensures maximum strength. While heating, there must be free air flow over the system to ensure removal of moisture.

Drying Refractory in Steam-Generating Boilers - Insulation

Thus, the dry-out schedules for drying refractory used on boilers must be tailored to the plant’s temperature-monitoring capabilities. 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.

Understanding Refractory Failure—A New Perspective

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.
