Circulating fluidized bed(CFB) boiler working principle

28/01/2015 · Circulating fluidized bed technology(CFB) also offers the flexibility of using both coal as well as biomass fuels. 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 combustion - ScienceDirect

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. Special design of the air nozzles at the bottom of the bed allows air flow without

Model Based Control of the Circulating Fluidized Bed Boiler

01/01/2013 · However, the twin revolutions of the TIF furnace creates more vigorous lateral solid mixing due to the periodic imbalance of the revolution strength. As illustrated in Fig. 1.8, at the centre of the bed a downward moving bed was created by adjusting air supply from the distributor. Wastes are fed to the centre of the bed surface, caught by the down-flowing solids and devolatilized rather slowly until they

01/01/2013 · The gas flow produced by combustion is equal to the flow of gas passing the cross section of the bed with a fluidization velocity u (m/s), [14.3] m f b g v = A c u ρ ( T b, P c) ( m 3 /s) where Ac is the cross section of the bed (m 2 ), Pc pressure of the bed (bar), and ρ is gas density (kg/m 3 ).
