【摘要】 独立焦化企业产量约占我国焦炭总产量的2/3。采用实地调研获取基础数据结合样品分析测试结果,对我国独立焦化生产原料和产品的碳含量与IPCC默认值进行了比较和分析。结合物料平衡和碳平衡,分析了3种类型焦炉生产碳排放因子的差别及其原因。计算得到碳排放因子0.259,碳排放强度为0.244 t(CO2)/t(焦),碳排放主要来源于燃料煤及自用焦炉煤气燃烧产生的烟气。更多还原

【Abstract】 The coke-producing process causes large amounts of carbon dioxide emission. However,the coke yield produced by the independent coking plants accounts for about 67% of the total production. On the basis of sites investigation and sampling analysis results,the carbon contents of raw materials and their products of the independent coking plants in China are comparatively compared with the default values by IPCC. The reason of different carbon dioxide emission factors of three kinds of coking chambers are analyzed based on the principle of mass balance with carbon balance. The results show that the carbon dioxide emission factor is 0. 259,and the emission intensity is 0. 244 t( CO2) /t( coke). Carbon dioxide emission is found mainly caused by the combustion flue gases of the fuel coal and coke oven gas self-used.更多还原
