Abstract
A fluidized bed steam generator and method of generating steam including a separate recycle bed in which a plurality of vertically stacked fluidized beds are disposed in a furnace enclosure and a heat recovery enclosure is defined adjacent the furnace enclosure for receiving the effluent gases from the fluidized beds. A fluidized bed is defined in the heat recovery enclosure and one or two separators are provided adjacent the heat recovery enclosure for receiving the effluent gases and separating the entrained solid particles therefrom. The separated solid particles are then injected into the fluidized bed in the heat recovery enclosure. Fresh fuel is supplied to the recycle bed and the material inventory and fluidizing velocity in the recycle bed is controlled.
