ABSTRACT:
A method of ameliorating high-temperature slagging conditions which result from impaction on the boiler interior surfaces of molten or semi-molten ash particles in flue gas resulting from the combustion of fuel. The method comprises adding a conditioner to the flue gas at or upstream of the high temperature region in the boiler system where slagging tends to occur, and thereafter causing the mixed flue gas and conditioner to flow through the region. Suitable conditioners include strontium carbonate, a mixture of zircon with copper oxychloride and a mixture of alumina with aluminum fluoride, zircon, or zirconyl chloride.
