Abstract: A furnace for heating workpieces in a controlled atmosphere comprises a bed of particles which can be fluidized. The bed is divided by a partition into a treatment zone and a combustion zone. Fuel and air are fed to the combustion zone and burned therein to heat the bed. A treatment gas which provides the required atmosphere is fed to the treatment zone and particles of the bed are permitted to migrate from one zone to the other, thereby carrying heat from the combustion zone to the workpiece in the treatment zone.

Abstract: A furnace for carrying out combustion of refuse or for reclaiming particles contaminated with combustible material comprises a bed of particles which is fluidized by feeding air and gaseous fuel into the bed. The refuse or contaminated material is fed into the bed and it is heated by combustion of the fuel therein. Incombustible residue is discharged from the bed over a weir. The furnace includes a heat exchanger for extracting heat from a part of the bed which can be fluidized selectively.
