摘要
采用热电联产形式的集中供热可以节约能源并减少大气污染物的排放。为真实反映并合理计算燃煤热电联产机组的环保效益,提出了一种基于㶲分析法的计算方法,用于分析计算燃煤热电联产机组的大气污染物排放量。提出了㶲分析法的计算基础,针对燃煤机组不同的蒸汽供应方式,构建了基于㶲分析法的大气污染物排放量计算模型;以某燃煤机组对某石化企业实施集中供热为例,采用所提方法进行了实例计算。
Central heating in co-generation of heat and power(CHP)can save energy and reduce the emission of air pollutants.In order to reasonably calculate the environmental benefits of coal-fired cogeneration unit,a calculation method based on exergy analysis method is proposed in this paper.Firstly,the calculation basis of exergy analysis method is put forward;secondly,the calculation model of air pollutant emission based on exergy analysis method is constructed according to different extraction steam of coal-fired units;finally,a coal-fired unit supplying central heating for a petrochemical enterprise is taken as an calculation example.
