循环流化床锅炉热力计算探讨

Study on Thermal Calculation of Circulating Fluidized Bed

对《层状燃烧及沸腾燃烧工业锅炉热力计算标准》（JB／DQ11060-83）中沸腾炉热力计算的部分内容进行讨论，导出沸腾层飞发含碳量和考虑未燃煤水分蒸发的沸腾层热平衡方程，并考虑循环流化床锅炉飞灰外循环，对《计算标准》中烟气烙、密相区热平衡等计算进行修正，使之可以应用于循环流化床锅炉热力计算。

This paper makes discussion on thermal calculation of CFBB specified in JB/DQ1o6o-83 Thermal Calculation Standard of Stoker Firing and Bubbling Combustion IndustrialBoiler. Bubbling Combustion flying ash carbon content and heat balance equation in con-sideration of unfired coal moisture steaming are induced. By considering outer circulation ofCFB fly ash, modifications are made for calculations of gas enthalpy and dence phase heat ba-lance in the above standard in order to apply in CFB thermal calculation.
