    摘要： A fluidized bed combustion system that can be operated or controlled under pressure is provided. To eliminate the erosion or abrasion to which heat exchangers located in a fluidized bed combustion chamber are subjected due to the flue dust contained in the flue gas, no thermal withdrawal or exchange takes place in the combustion chamber of the inventive fluidized bed combustion system, although the reaction conditions remain the same. At least one controllable line for returning to the combustion chamber part of the flue gas, if necessary cooled by heat exchangers variously arranged outside the combustion chamber, branches off from the flue gas line downstream of a dust separator that is disposed in the flue gas line downstream of the combustion chamber. The main area of application is the production of electrical energy and heat for the generation of steam, as process heat, or as heat for a remote site, by means of a fluidized bed combustion system that can be operated or controlled under pressure.
