My question is related with refractories use in waste incineration. In incineration, we use many type of waste at 1,100°C and cause a molten slag formation. What type of effect on refractories (alumina/silica) occurs under these conditions and is there any effect on the flue gas velocity on refractories erogen?
Have an insight or suggestion?

Re: Waste incineration and refractories20 December 2006 at 1:29pmWhen incinerating with molten salts at 1,100°C, refractory life can be impacted significantly by the type of refractory used. At this temperature, salts can vaporize, penetrate the refractory structure and condense behind the surface. Eventually, this can cause the refractory to spill, causing significant damage. Proper refractory selection is necessary when operating at these high temperatures with molten salt. In incinerators, generally speaking, flue gas velocities have very little impact on refractory erosion.
