15ton hour coal fired circulating fluidized bed steam boiler
16-06-2015
15ton per hour coal fired CFB boiler can efficiently use fuels such as low rank lignites and sub bituminous coals that typically produce a lot of ash and are difficult to use in other types of coal fired boilers.

Circulating Fluidized Bed (CFB) steam boiler
CFB technology now involves larger and more complex steam generators with multi-boiler installations. Given that CFBs have a certain degree of uniqueness and complexity in design and operation, it is similarly correct to assume that simulating them properly requires very effective modeling software.
Fluidized Bed Combustion (FBC) steam boiler
Fluidized bed combustion (FBC) steam boiler for biomass boiler has emerged as a viable alternative and has significant advantages over conventional firing system and offers multiple benefits–compact boiler design, fuel flexibility, higher combustion efficiency and reduced emission of noxious pollutants such as SOx and NOx. The fuels burnt in these boilers include coal, washery rejects, rice husk, bagasse & other agricultural wastes. The 15ton hour coal fired fluidized bed boilers have a wide capacity range- 0.5 T/hr to over 100 T/hr.
When an evenly distributed air or gas is passed upward through a finely divided bed of solid particles such as sand supported on a fine mesh, the particles are undisturbed at low velocity. As air velocity is gradually increased, a stage is reached when the individual particles are suspended in the air stream – the bed is called “fluidized”.
If sand particles in a fluidized state is heated to the ignition temperatures of coal, and coal is injected continuously into the bed, the coal will burn rapidly and bed attains a uniform temperature. The pressurized circulating fluidized bed combustion (PCFBC) takes place at about 840 OC to 950 OC. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided.
The lower combustion temperature is achieved because of high coefficient of heat transfer due to rapid mixing in the fluidized bed and effective extraction of heat from the bed through in-bed heat transfer tubes and walls of the bed. The gas velocity is maintained between minimum fluidization velocity and particle entertainment velocity. This ensures stable operation of the bed and avoids particle entertainment in the gas stream.
