A means and method of controlling the load turn-down in a fluidized bed combustor including a fluidized combustion bed having an independent fluidization air source. A separately fluidizable heat transfer bed surrounds the fluidized combustion bed. By independently adjusting the fluidization of the heat transfer bed, the load turn-down of the fluidized bed combustor can be accurately and efficiently controlled. In an alternative embodiment, one or more heat transfer beds are positioned in and surrounded by the combustion bed. Conduits are then positioned within the heat transfer beds to carry a circulating and heat-conducting medium therethrough.
