Fluidised bed combustor or reactor - passes combustion-supporting gas upwardly through bed of particulate material for entraining and separating outside housing

摘要

A perforated plate disposed in a housing supports a bed of particulate fuel material. A combustion supporting gas is passed upwardly through the perforated plate to fluidise the particulate material and entrain the relative fine particulate material before discharging from the housing along with the gaseous products of combustion. The entrained particulate material is separated from the gas, and is agglomerated outside the housing before being passed back to the bed.
