    • In a process and a fluidized bed furnace installation for performing the process for the combustion of carbonaceous materials in a fluidized bed reactor with an atmospheric or pressurized, circulating fluidized bed, wherein solids are circulated in a circulation system consisting of a fluidized bed reactor, at least one separator, and at least one return line, and wherein solids are withdrawn from the circulation system, and wherein the stack gases are discharged downstream of the separator, and wherein combustion heat is removed at least by way of heating surfaces of the fluidized bed reactor and by way of stack-gas-exposed heating surfaces downstream of the separator, the invention provides that a partial stream of solids withdrawn from the circulation system is admixed to the stack gases or waste gases, exiting from the separator, upstream of the heating surfaces for the removal of heat from the stack gases.
    • 在用于在具有常压或加压循环流化床的流化床反应器中进行碳质材料燃烧的方法和流化床炉装置中,其中固体在由流化床反应器组成的循环系统中循环, 至少一个分离器和至少一个返回管线,并且其中固体从循环系统中排出,并且其中堆叠气体被排放到分离器的下游,并且其中至少通过加热流化床的表面去除燃烧热 反应器,并且通过在分离器下游的堆叠气体暴露的加热表面,本发明提供从循环系统中排出的固体的部分物流与叠加的气体或废气混合,从加热器的上游离开分离器 用于从堆叠气体中除去热量的表面。
