| 摘 要： | 论述了循环流化床锅炉燃用石油焦和煤添加石灰石时对锅炉热效率计算的影响．通过分析循环流化床锅炉燃用石油焦和煤混合燃料添加脱硫剂时的物料平衡和灰平衡。得出采用国标GB10184-88《电站锅炉性能试验规程》计算锅炉热效率时，要对热量、烟气量和灰量进行修正。结合一台220t／h CFB锅炉实例，计算出实际测试工况下的热效率为89．5％。

| Abstract: | The effects of desulfurization with limestone injection on the thermal efficiency calculation of CFB boiler firing the blending fuel of petroleum coke and coal are discussed in the paper.Material balance and ash balance are analyzed.It is concluded that for calculating CFBB thermal efficiency with the National Standard GB10184-88 ,the quantity of heat,flow rates of the flue gas and the ash need to be modified accordingly.Taking a 220 t/h CFB boiler as a sample,its thermal efficiency is 89.5%. |
