Fluidized Bed Boiler - an overview | ScienceDirect TopicsGet A Quote
Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air. There are two types of fluidized beds: in bubbling fluidized beds the bed particles are kept in suspension at relatively low fluidization velocities whereas in circulating fluidized beds, particles are carried out of the bed at higher fluidization velocities and are separated in a cyclone and reintroduced back into the bed.Get A Quote
The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷(Calorific value of natural gas x Boiler …Get A Quote
Basu and Fraser  have defined the CFBC boiler as follows: "A circulating fluidized bed boiler is a device for generating steam by burning fossil fuels or biomass in a combustion chamber operated under special hydrodynamic condition.Get A Quote
Most of the early BFBs used tubular air heaters to minimize air leakage that could occur as a result of relatively high primary air pressures required to suspend the bed. Recent designs have included regenerative type air heaters. Circulating fluidized bed combustor . A typical CFB arrangement is illustrated schematically in figure.Get A Quote
