大型贫煤和烟煤锅炉 NO_x 排放特性的研究

Study of the NO x Discharge Characteristics of Large Lean and Bituminous Coal Boilers

针对２台分别燃用贫煤和烟煤的３００ＭＷ锅炉（均采用ＷＲ型燃烧器）ＮＯｘ排放特性进行了研究。分析了这２种锅炉在满负荷和低负荷时ＮＯｘ排放量的差别，并指出了燃用贫煤锅炉比燃用烟煤锅炉ＮＯｘ排放量高的原因。

The property of NO x emissions of two boilers(used the WR burners),alternately combusting semi anthracite and bituminous coal,was investigated.The authers study and analyse the difference of NO x emissions between the boilers(running in full load and low load),and present the reasons why the NO x emissions of the boiler combusting semi anthracite coal is more than one combusting bituminous coal.
