AP-42 Section 1.6 Wood Residue Combustion in Boilers

A later innovation in wood firing is the fluidized bed combustion (FBC) boiler. A fluidized bed consists of inert particles through which air is blown so that the bed behaves as a fluid. Wood residue enters in the space above the bed and burns both in suspension and in the bed. Because of the large thermal mass represented by the hot inert bed

Fluidized Bed Combustion System - an overview

Paul Breeze, in Energy from Waste, 2018. Fluidized Bed Combustors. A fluidized bed combustion system is a special type of combustor that was originally developed as a reactor for the chemical process industry. The combustor exploits the rapid mixing properties of a fluid, converting a mass of solid particles into a "fluid" by pumping air through the bed of particles from below.
