Tom, I think a new class of refractory should be created and included. Catalytic refractory. In my boilers, I use duraboard and cerablanket covered with expanded stainless. As gasses comingle, they burn in the fibers and radiate quite an amount of radiation back into the fuel pile. I believe this is the future of refractory. It is proven, and on the market today. It just isnt in the books yet.
