Jan 15, 2019 · The fluidized bed combustion takes place at a temperature of 840°C to 950 °C. Since the temperature is below the ash fusion temperature, melting of ash and associated problems are avoided. There are three types of fluidized bed combustion boilers: 1. Atmospheric fluidized bed combustion system (AFBC) or Bubbling fluidized bed combustion (BFBC)

Circulating Fluidized Bed - CFB Boiler Process - YouTube

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 Combustors for Biomass Boilers - ASME

Boiler engineers can choose between two main types of fluidized-bed boilersbubbling 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.

Fluidized bed combustion - Wikipedia

Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed. FBC
