Circulating Fluidized Bed (CFB) – In a CFB boiler, the crushed coal, normally mixed with crushed limestone, is fluidized by passing pre-heated combustion air upward through a distributor plate.
A coal index is proposed to describe the coal rank, defined by the ratio of the volatile content to the coal heat value, is a useful parameter to analyze the char burnout. The carbon content in the fly ash depends on the coal rank strongly. CFB boilers burning anthracite, which has low coal index, usually have high carbon content in the fly ash.
Fouling in a CFB is typically less of a concern than in other boiler types. The hot loop of the CFB is kept clean by circulating bed material and the low combustion temperature avoids ash melting, greatly reducing the fouling potential in the back-pass. The high efficiency separation of ash in the cyclone makes convective heating surfaces in a
