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。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。
Thermal power plant is an important energy production sector for steel companies. The CHP’s carbon emissions are related to the overall carbon emission reduction effectiveness of enterprises. Carbon emissions per unit of energy products using indicators, combined with the analysis to evaluate the thermal power plant carbon emissions, carbon emissions per unit of energy products will be decomposed into minimum emissions and additional emissions study. The results show that CHP can reduce the carbon emission of iron and steel enterprises through energy cascade utilization, improve energy conversion efficiency and reduce the use of fossil fuels.
