ABSTRACT:
A fluidized bed combustion system and method in which a recycle heat exchange section is located within an enclosure housing the furnace section of the combustion system. The flue gases and entrained solids 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 to the recycle heat exchange section. The recycle heat exchange section includes a bypass chamber for permitting the separated solids to pass directly from the separator to the furnace section. A heat exchange is provided in the recycle heat exchange section to transfer heat from the separated material in the recycle heat exchange section to a fluid flow circuit for heating the fluid flow circuit and reducing the temperature of the separated material. The separated material of the recycle heat exchange section is then passed back to the furnace section.
