钢铁企业热电厂碳排放的评价研究

摘要

热电厂是钢铁企业重要的能源生产部门,热电联产的碳排放量关系到整个企业碳减排成效.采用单位能源产品碳排放量指标结合(火用)分析来评价热电厂的碳排放量,将单位能源产品碳排放量分解成最小排放量和附加排放量进行研究.结果表明:热电联产通过能源梯级利用,提高能源转换效率,减少化石能源使用,有利于实现钢铁企业减少碳排放.%The thermal power plant was an important energy production department of iron and steel enterprises, carbon emission from the thermal power plant influenced carbon emission reductions of I-ron and steel enterprises. Used carbon emissions index of the unit energy products and the exergy analysis methods to evaluate carbon emissions, the carbon emissions index was divided into two parts minimum emissions and additional emissions. The research indicated that combined heat and power was helpful to realize reducing carbon emissions for the steel enterprises by improving cascade energy conversion efficiency, reducing fossil energy use and cascade utilization of energy.
