<p>A steam generator in which a plurality of vertically spaced fluidized beds are provided in a single enclosure, with one boundary wall of the enclosure having openings therein for permitting the discharge of effluent gases from the fluidized beds. A heat recovery enclosure is defined adjacent the beds for receiving their effluent gases and a fluidized bed is disposed in the heat recovery enclosure. A separator system is disposed adjacent the heat recovery enclosure and receives the effluent gases from the heat recovery enclosure and separates the entrained solid particles therefrom. The separated particles are reinjected into the fluidized bed in the heat recovery enclosure.</p> |
