摘　　要：针对富氧燃烧锅炉增加了尾部再循环烟气和空气分离器抽出的氧气特点,对富氧燃烧锅炉进行了热平衡计算建模,并以常规燃烧锅炉热平衡计算方法为基础,提出了富氧燃烧锅炉热平衡计算方法方法,并比较了不同氧浓度对富氧燃烧锅炉热平衡计算结果影响规律。所得研究结果为开展富氧锅炉热力计算提供了理论基础。Based on the characteristics of the oxy fuel combustion boilers with the mixture of the recirculation of the exit flue gas and the fresh pure oxygen separated by the air compressor as the burn gas, the method of the heat balance calculation of the oxy fuel combustion boiler was suggested in the base of the heat balance calculation method of the air combustion boil- ers. The influence of the concentrations of the oxygen for the heat balance calculation of the oxy fuel combustion was studied.
