Another example is given in where increased fouling deposits, usually composed of sulfates and chlorides, were observed in a circulating fluidized bed boiler with the increase of the RDF cofiring share. Anyhow, even when increased slagging and fouling propensity was found, authors concluded that co-combustion of coal and WDF in power plant was feasible.
Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone.
Circulating Fluidized Bed (CFB) Boiler capacity: for CFB steam boiler upto 250 ton, CFB hot water boiler upto 170MW. CFB boilers offer benefits such as low pollution, high-efficiency combustion, space saving, and high maintainability. ZG's CFB Boiler technology is expected to be at the forefront of next-generation environmentally conscious boilers.
The selection of type of fluidized bed boiler depends on the fuel type, steam condition, etc. BFB is suitable for fuel with low fuel ratio and/or low heating value such as biomass fuel or waste fuel. On the other hand, CFB is suitable for fuel with high fuel ratio such as anthracite, or for waste fuel firing under the high steam condition.
