循环流化床锅炉炉膛内辐射换热计算方法探讨

Discussion on Calculation Method of Radiation Heat Transfer in the Furnace of CFBB

对比了两种循环流化床（ＣＦＢ）锅炉炉膛内求取辐射换热系数的方法；计算表明：炉内稀相区辐射换热系数占总传热系数的６５％左右．

The two methods which obtained the coefficient of radiation heat transfer in the furnace of CFBB had been compared.It had been shown by calculating that the coefficient of the radiation heat transfer in the rare phase zone of the furnace was about 65% total heat transfer coefficient.
