摘要:

摘要:天山铝业有限公司自备电厂 #2锅炉NOx排放质量浓度高达500mg/m3(标态,干基,折算到6% O2)左右,为降低脱硝成本及防止空气预热器堵灰影响锅炉整体出力,进行宽煤种适应性及深度低氮、防渣燃烧改造。改造后的燃烧器未出现结焦情况,NOx质量浓度有效降低且波动趋于稳定。

Abstract:For the Self generation Power Plant of Tianshan Aluminum Company Limited, the mass concentration of NOx  which emissions from the No. 2 boiler reaches up to 500mg/m3(standard state, dry basis, reduces to 6%O2). In order to reduce the denitration cost and prevent the clogging of air preheater that influence the overall output of boiler, a retrofit of wide coaltype adaptability,deep low nitrogen and anti clogging combustion was conducted.After the retrofit,the coking phenomenon of burner is not found any more and the mass concentration of NOx is effectively reduced with small fluctuation.
