摘要:火电行业是大气污染物排放贡献以及减排潜力较大的行业,被列为“十三五”期间吉林省开展节能减排的重点行业。文章通过脱硫脱硝、超低排放和电力关闭三方面主要改造工程来测算SO2和NOx的减排潜力。结果显示:“十三五”期间吉林省火电行业SO2和NOx削减总量分别为7.27万t和17.12万t,吉林市和长春市是减排贡献最大的两个行政区,减排前景乐观。

Abstract:The thermal power industry is an industry which is not only with great contribution to the emission of air pollutants but also with great potentiality of reduction, so it is defined as a key industry for energy conservation and emission reduction in Jilin province during the 13th five-year plan period.In this paper,the potentiality of reduction of SO2 and NOx is calculated through three major renovation projects of desulfurization and denitration, ultra-low emission and power shutdown.The results show that the total reduction of SO2 and NOx in the thermal power industry in Jilin province during the 13th five-year plan period is 72,700 tons and 171,200 tons, respectively.Jilin City and Changchun City are the two administrative regions with the largest contribution to emission reduction,and the emission reduction prospects are optimistic.

1 概述
吉林省位于中國东北地区中部,是国家“一带一路”向北开放的重要窗口,同时是重要的东北老工业基地。2014年,全省工业增加值达到6 492.93亿元,占GDP和二产的比重分别为47%和89.1%,比2010年分别提高1.7和1.9个百分点[1],预计“十三五”仍将持续增长。工业的发展离不开其能量和动力——电力,社会的快速进步也使得全民对电的需求量不断增长,给电力行业带来了新的挑战。而火电行业是电力行业发展的重心,全国每年用电总量的70%都是火电行业的贡献,火电行业消耗了大量的资源和能源,排放的污染物对大气环境产生了严重的影响[2]。
经济的快速发展必然对资源环境的承载产生巨大的压力,同时生态环境现状与人民群众的需求和期待差距较大,“十三五”期间经济社会发展不平衡、不协调、不可持续的问题仍然突出,因此本研究在全面了解目前主要大气污染物排放现状的基础上,通过对全省未来5年因经……
