为准确合理地确定适合于钢铁行业实际的碳排放系数,通过碳平衡算法求出了各工序的碳排放量,然后按碳排放系数的定义反算出了各工序的碳排放系数.同时,通过对某大型钢铁企业焦化、烧结、炼铁3个典型工序的原料产能的实测数据调查,首先基于碳平衡方程计算出典型工序的碳排放量,然后由碳排放量计算其碳排放系数.最后以该大型钢铁企业2009年的调查数据为例,按本方法计算出的焦化、烧结、炼铁工序的碳排放系数分别为0.518、0.210、1.375,与IPCC提供的默认值(0.56、0.20、1.35)极为吻合.这一结果表明,该方法用于我国钢铁行业碳排放系数体系的建立是可行的.
In order to accurately and reasonably determine the carbon emission factors suitable for the steel industry, the carbon emissions of each process were calculated by the carbon balance algorithm, and then the carbon emission coefficients of each process were calculated according to the definition of the carbon emission coefficient.At the same time, First, a typical steelmaking company coking, sintering, ironmaking three typical processes of raw materials production survey data, first based on the carbon balance equation to calculate the typical process of carbon emissions, and then calculate the carbon emissions from the carbon emission coefficient.Finally, For example, according to the survey data of large iron and steel enterprises in 2009, the carbon emission coefficients of coking, sintering and ironmaking processes calculated by this method are 0.518, 0.210 and 1.375, respectively. The default values (0.56, 0.20, 1.35) This result shows that this method is feasible for the establishment of carbon emission coefficient system in China’s steel industry.
