Abstract
A fluidized bed combustion system and method in which a recycle section is located integrally with the furnace section in an enclosure and operates as a combustor. Heat exchange surfaces are provided in at least one compartment of the combustor/heat exchanger for removing heat from the solids, and a bypass compartment is provided through which the solids directly pass to the furnace during start-up and low load conditions. Fluidizing air is discharged at the internal recirculation of the solids and a partition is located in the central portion of the furnace enclosure for introducing secondary air.
