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 plants are capable of burning a variety of low-grade solid fuels, incl
The first step is to change the bark boiler to a fluidized bed of suitable size. Here, a bubbling bed is the most likely system to be used to produce steam for the mill. The second step is to connect the bubbling bed to a circulating bed, transform the BFB boiler to a gasifier, and introduce a primary dryer that reduces the moisture content of
Jan 15, 2019 · The fluidized bed combustion takes place at a temperature of 840°C to 950 °C.

Fluidized Bed Combustion FBC Boiler Animation. MECHANISM OF FLUIDISED BED COMBUSTION If the sand, in a fluidized state, is heated to the ignition temperature of the fuel and the fuel is injected continuously into the bed, the fuel will burn rapidly and the bed attains a uniform temperature due to effective mixing. This, in short is fluidized bed combustion.
