ABSTRACT:
A fluidized bed heat generator includes a combustion reactor vessel containing a recirculating flow of fluid entrained fine solid particulate material with a dense bed section of limited space in the vessel containing a fluidized coarse solid particulate material retained therein. A recirculating path defined in part within the vessel and externally thereof provides for a recirculating flow of said fine solid particulate material into and out of the combustion vessel and through the coarse material of the dense bed section. Air or gas is supplied for fluidizing the coarse solid particulate material in the dense bed section and for entraining the fine solid material to flow through the dense bed and around the recirculating path. A separator system is provided for maintaining both the fine solid particulate material and the coarse solid particulate material in the dense bed section within selected particle size ranges to promote maximum efficiency of operation at variable loads.
