2019-11-9 · Fluidized bed boilers. Fluidized bed boilers use the principle of burning fuels in a fluidized bed. A fluidized bed creates conditions suitable for the uniform combustion of fuel throughout its volume, which means, as a final result, more perfect fuel burn-up (high efficiency of a fluidized bed boiler) at lower combustion temperatures and whilst reducing the production of harmful waste gases

bubbling fluidized bed | BioEnergy Consult

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.
