In a fluidised-bed combustor, combustion occurs when the mixture of fuel, a sorbent and fuel ash particles is suspended by using a continuous stream of primary combustion air to create turbulence in the bed. The gas cushion between the solids allows the particles to move freely, giving the bed a liquid-like (fluidised) characteristic.

Fluidized-bed furnaces operate in quite a different manner from fixed-bed furnaces and have a number of advantages associated with them. Fluidized-bed combustion uses silica sand (lime stone, dolomite, or other noncombustible materials) for bed material, keeps fuel and sand in furnace in boiling state with high-pressure combustion air, and ...
Production of direct reduced iron (DRI), particularly with green hydrogen, is a key pathway to the decarbonization of the iron and steel industry. However, the sticking tendency during the production of DRI creates serious operational issues and limits production outputs. Coating inert materials on the surface of iron ores can act as a …
