ABSTRACT:
A fluidized bed steam generation system and method in which an external heat exchanger is located adjacent a furnace section. A mixture of flue gases and entrained particulate materials from a fluidized bed in the furnace section are separated and the flue gases are passed to a heat recovery section and the separated particulate material back to the fluidized bed in the furnace section. Particulate material from the fluidized bed in the furnace section is circulated through the external heat exchanger to add heat to water, steam or a steam/water mixture before the material is passed back to the furnace section. Water is passed through the furnace section, the heat recovery section, and the external heat exchanger to convert the water to steam.
