焦炉加热时过量空气系数对氮氧化物生成量的影响

摘要

对某6m焦炉燃烧室单对立火道进行数值计算，计算结果与设计值基本吻合，在此基础上模拟6种不同工况下立火道内的燃烧状况，讨论了过量空气系数对氮氧化物生成的影响。%By calculating single-pair vertical flue of6m battery, the result is almost consistent with the design value .Accordingly ,this paper has simulated six different heating modes in vertical flue as different work state and discussed the coefficient of excess air influence on nitrogen oxides genera -tion.
