摘　　要：对NOx排放影响因素之间的模糊性和不确定性采用模糊层次分析法（FAHP）进行分析。通过对各影响因素两两间隶属度的判别并结合现场试验，构造了反映人的思维判断和客观事实一致性的模糊矩阵，定量计算出某电厂215MW机组锅炉NOx排放影响因素的权重指标，找出NOx排放最强影响因素。据此，对锅炉进行了针对性的燃烧调整．使NOx排放降低了10％～15％，效果显著。In view of fuzziness and uncertainty among affecting factors upon NOx emission,analysis has been carried out by using the Fuzzy Analysis Hierarchical Procedure （FAHP）. Through judgement of the subordinating degree between every two affecting factors,and combining with tests in the field,a fuzzy matrix reflecting the consisitency of people＇s thoughts and objective facts has been constructed, the weight indices of affecting factors upon NOx emission from boiler of 215 MW unit in one power plant being quantitatively calculated ,and the strongest affecting factor being found. Based on this,corresponding adjustment for boilers has been carried out,making the NOx emission to be decreased by 10 -15 %, having remarkable effectiveness.
