高炉CO2排放量的计算方法探讨 邹忠平1,郭宪臻2,王刚1,项钟庸1,王瑞玲2 (1. 中冶赛迪工程技术股份有限公司 炼铁事业部,重庆,401122; 2. 安阳钢铁集团公司,河南 安阳,455004) 摘要:通过对比国际钢协CO2排放计算方法,提出高炉CO2排放计算应采用实测的CO2排放因子,并分为工序CO2排放和吨铁CO2排放2种算法,前者为高炉工序直接的排放,而后者包括焦化,烧结等上游工序的间接排放.这2种算法可用于不同的用途,以满足钢铁厂和行业的不同需要.按照该计算方法,国内某2000级高炉的工序CO2排放量为1 185.9 kg/t铁,吨铁CO2排放量为1 666.9 kg. 关键词......
