摘要：A fluidized bed combustion system and method in which a recycle heatexchange section is located within an enclosure housing the furnace section of thecombustion system. The flue gases and entrained solids from a fluidized bed in thefurnace section are separated and the flue gases are passed to a heat recovery sectionand the separated particulate material to the recycle heat exchange section. The recycleheat exchange section includes a bypass chamber for permitting the separated solids topass directly from the separator to the furnace section. A heat exchange is provided inthe recycle heat exchange section to transfer heat from the separated material in therecycle heat exchange section to a fluid flow circuit for heating the fluid flow circuit andreducing the temperature of the separated material. The separated material of therecycle heat exchange section is then passed back to the furnace section.
