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 â€śfluidâ€ť by pumping air through the bed of particles from below. This agitation of the bed causes the particles to become â€śfluidizedâ€ť so that they mix rapidly with one â€¦
04-03-2020· In fluidized bed combustion, rapid mixing ensures uniformity of temperature. The main advantage of fluidized bed combustion system is that municipal waste, sewage plant sludge, biomass, agricultural waste and other high moisture fuels can be used for heat generation.
OverviewFluidized-bed combustion is a process in which solid particles are made to exhibit fluid-like properties by suspending these particles in an upwardly flowing evenly distributed fluid stream. Fuel flexibility and reduced emissions are the benefits of fluidized bed combustion.

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties.
In fluidized-bed combustion, a bed of crushed solid particles (usually six millimetres or less) is made to behave like a fluid by an airstream passing from the bottom of the bed at sufficient velocity to suspend the material in it.
Fluidized Bed Combustion (FBC Boiler) â€śFluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.â€ť A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.
