    combusted primarily in fluidized bed combustion (FBC) boilers because of its high ash content and low heating value. Combustion of anthracite coal on a traveling grate is characterized by a coal bed 3 to 5 inches in depth and a high blast of underfire air at the rear or dumping end of the grate. This highLearn More

    Among the early waste-heat recovery incinerators were low-pressure boilers, high-pressure boilers, and water wall furnaces. Low-pressure boilers were the first to be developed and the majority of them had boilers located in the combustion chamber which lowered combustion efficiency as a result of excessive cooling of the furnace [49,58] .Learn More
