摘　　要：当前复合燃料温室气体(GHG)排放量的计算普遍采用IPCC排放因子法,此法的运用需要依赖准确的燃料消耗计量、燃料氧化率和燃料低位热值等数据,其缺省因子是否适合有待商榷。本文通过采用实地监测手段,在获得了企业固定排放源设备的相关参数后,采用IPCC排放因子法、质量平衡法、时间比法、负荷法和热值分配法等几种方法对企业GHG排放量进行了计算。结果显示:IPCC排放因子法的计算结果并不能准确地反映企业温室气体的排放情况,而热值分配法可以较好地对燃烧复合燃料的固定燃烧源GHG排放量进行计算。建议有条件的地区采用监测法对固定燃烧源GHG排放量进行计算,而采用热值分配法对燃烧复合燃料的固定燃烧源拓展时间段的GHG排放量进行计算。IPCC emission factor method is a universal scheme to quantify the greenhouse gas （GHG） emissions at present, but we doubt whether this quantitative method can be used in our country because its ac curacy depends heavily on the consumption measurement, oxidation rate and low calorific value of fuel. Through field monitoring, this paper obtains the related parameters of fixed emission source equipment in enterprises, such as temperature, pressure,etc. And then the paper calculates the GHG emissions by IPCC emission factor method, mass conservation method, time rate method, load method and calorific value allo- cation method respectively. The result shows that the IPCC emission factor method cannot precisely reflect the GHG emissions;however,the calorific value allocation method obtains the better result. The paper rec- ommends using monitoring method to calculate the GHG emissions of fixed combustion source and using calorific value allocation method to calculate the GHG emissions of the fixed combustion source that con sumes composite fuel in the expanded time period.
