After starting an aq incinerator plant, we took a shut down. During the inspection we found a change in brick lining (230 to 125). In our system, we use aq waste and a small amount of solvent. The waste contains Cl, Na, Mg, P, S, CL, N, etc. Are there any effects on high alumina brick lining due to molten slag or chemical attack at 1,100ºC?
Have an insight or suggestion?

Re: Brick lining variation3 January 2007 at 1:29pmHigh alumina refractory is more suited for high chlorine wastes not inorganic salts wastes. At 1,100ºC, salts such as Na and Mg can attack refractory and cause spalling of the refractory. The extent of attack may depend on quantity of salt, physical arrangement, etc.
