摘　　要：以95台中小型烟煤层燃炉(≤70MW)的燃料特性分析数据和颗粒物(PM)排放实测数据为基础,利用统计分析方法及SPSS13.0统计分析软件,分析了锅炉出力W、过量空气系数α、燃煤灰分含量w(A)对燃烧过程PM初始排放因子的影响,研究了PM初始排放因子的变化规律.结果表明,在锅炉运行负荷≥80%的条件下,基于燃料消耗量、燃料发热量和灰分含量的PM初始排放因子EF0C、EF0H和EF0A基本上与W无关;EF0C、EF0H随α和w(A)的增加而增大,EF0A随w(A)增加而减小.3种影响因子由强到弱的顺序分别为EF0C:w(A)>α>W;EF0H:w(A)>α>W;EF0A:w(A)>α>W。The influences of boiler output（W）,excess air coefficient（）,coal ash content（w（A）） on particulate matter（PM） initial emission factors in coal combustion were analyzed by statistical analysis method and SPSS13.0 using PM actual test data and coal analysis data from 95 medium and small layer soft coal-fired boilers,actual capacity of boilers 70 MW.The changing characteristics of PM initial emission factors was also studied.The results indicated the PM initial emission factors EF0C,EF0H,and EF0A based on fuel consumption,coal lower heating value and coal ash content were not related with W under the condition of boiler loads 80%,and EF0C,EF0H increased slightly with and w（A） increasing.Moreover,EF0A decreased with w（A） increasing.The orders from strong to weak of three influencing factors were w（A） W for EF0C,w（A） W for EF0H,and w（A） W for EF0A respectively.
