VAPOR GENERATING SYSTEM UTILIZING FLUIDIZED BEDS

摘要

A vapor generating system in which a plurality of vertically stacked beds of particulate material containing a solid fuel are disposed in a housing. Pressurized air is passed through each of the fuel beds to fluidize the beds and thus promote the combustion of the fuel and maintain the beds at predetermined temperatures while a heat exchange medium is circulated in a heat exchange relation to the beds. The air is pressurized by an air compressor driven by a gas turbine which, in turn, is driven by the flue gases from the fluidized beds.
