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.

But castable holds up better than kaowool and it is usually a less expensive option. Kaowool generally heats up and cools down faster which has its advantages but it also does not hold up as well to rough handling. Many people face it with a layer of refractory mortar which gives it a bit more resilience.
