摘　　要：循环流化床锅炉在炉膛、分离器和回料器组成的灰循环系统中 ,存在大量的循环灰量。它是载热体 ,从炉膛吸入或放出热量。虽然循环灰温降不大 ,然而循环灰量却极大 ,严重影响燃烧产物的热平衡。在循环流化床锅炉热力计算时 。The circulating fluidized bed boiler exists a great number of circulating ash in the ash circulating system, including furnace, separator and loop seal pot. It is a heat carrier, absorbing or releasing heat from the furnace. Although its temperature drop is not too big, while the amount of circulating is enormous, finally it have seriously influence on the heat balance for combustion products. In thermal calculation for CFB boiler, It must be taken into consideration.
