Boiler Refractory Installation and Startup Guide
Dec 13 2018 · Refractories are one of the most overlooked components of boiler systems. They re heat resistant materials that make up the lining of boilers and other equipment—like furnaces. While they re integral to running and maintaining commercial and industrial boilers they are also a leading cause of boiler outages and energy losses.

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.
