Technology Overview: Circulating Fluidized-Bed Combustion

Pennsylvania has also investigated circulating bed boiler concepts.^9 A deep recirculating fluidized-bed combustion boiler (Figure 20) was conceived by Westinghouse as an alternative to conventional atmospheric and pressurized fluid bed units. Westinghouse developed a design for this concept operated at elevated pressure.

In CFBC boilers, combustion has been separated from heat transfer by adding heat exchangers in a back pass. 5%. Intensive mixing of fuel and inert material in the fast fluidization regime and smaller furnace cross section make it possible for circulating fluidized bed boilers

What Is The Working Principle of CFBC Boiler

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

Fluidized bed - Thermopedia

Boilers with grates use fixed beds, fluidized bed combustion boilers use bubbling fluidized beds or turbulent regime (in this case with fly ash recirculation), circulating fluidized bed boilers use the fast fluidization regime and pulverized coal combustion boilers work in the pneumatic conveying regime.

Circulating fluidized bed combustion for biomass boiler

Efficiency of the CFB Combustion Process. Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed.
