Fluidized bed combustion - Wikipedia

2019-9-27 · Fluidized bed combustion (FBC) 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 (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

The bubbling fluidized-bed (BFB) gasifier is shown in Figure 9.4 in which the gasification agent is injected from the gasifier bottom and the producer gas exits from the gasifier top while the solid fuel is introduced to the bed. This type of gasifier is characterized by the bubbling of bed material and solid fuel by flowing gas through it when the gas velocity is sufficiently high.

Stanislav S. Naboychenko, in Handbook of Non-Ferrous Metal Powders (Second Edition), 2019. Fluidized Bed Furnaces. The reduction process is accelerated 3–4 times when using fluidized bed furnaces due to increasing the contact area between the powder and the gas-reducer. However, the reduction operations are more difficult to control than reduction in a conveyor furnace.

Fluidized Bed Combustion takes place when the forced draught fan supplies air to the Furnace of the Boiler. In the furnace, and is (used for Bubbling phenomenon) placed on the Bed and is heated before fluidization, the air enters the bed from the nozzles fitted on the Furnace Bed. And above the nozzles; the sand opposes the upward motion of the

Fluidized Bed Boilers. The basis for a fluidized bed combustion system is a bed of an inert mineral such as sand or limestone through which air is blown from below. The air is pumped through the bed in sufficient volume and at a high enough pressure to entrain the small particles of the bed material so that they behave much like a fluid.
