摘要:

摘要:为保证污染物排放指标达到超低排放标准,华能铜川照金电厂一期2 × 600 MW 燃煤发电机组进行了烟气超低排放改造。提出了低低温省煤器+湿烟囱改造方案及管束式换热器(MGGH)+ 干烟囱改造方案,分别从经济性、施工工期、施工难点及环境影响等方面对2个方案进行了对比分析, 经综合比较,推荐MGGH+干烟囱改造方案。

Abstract:

Abstract:2×600MW coal fired generating unit of Huaneng Tongchuan Zhaojin Power Plant phase 1 starts to have modification for flue gas emission in order to make sure to meet standard for ultra low discharge of pollutants.This paper brought up two plans and analyzed them through investment,economy,construction period,construction difficulties,environment and other factors.One is low temperature economizer plus wet chimney modification,the other one is MGGH plus dry chimney modification,which is recommended after an integrated assessment.
