摘　　要：通过分析过量空气系数α与排烟热损失、化学不完全燃烧热损失和固体不完全燃烧热损失的关系,指出了α对锅炉燃烧效率的的重要性,并推导出锅炉运行时最佳过量空气系数αzj的计算公式。By the theoretical analysis of the relation between excess air coefficient α and heat loss of exit gas, heat loss of mechanism inadequacy burning, heat loss of the inadequacy burning for chemistry. That α has great influence on boiler combustion efficiency was found out, and concludes a new way to ascertain the optima excess air coefficient during the operation of boiler.

关 键 词：锅炉 过量空气系数 热损失 节能
