A fluidized bed combustion system and method in which a recycle heat exchanger is located adjacent the furnace section of the recycle heat exchanger. Heat exchange surfaces are provided in one compartment of the 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. A separate cooling compartment for the separated solids is disposed in the recycle heat exchange and valves are provided to selectively control the flow of solids between compartments.
