摘要:

燃煤电厂是大气Hg排放的主要来源之一,基于文献调研,分析了燃煤电厂烟气中Hg的来源及生成、燃烧后现有设备协同脱Hg技术和吸附剂喷射脱Hg技术、主要离线测试方法、超低排放实施前后燃煤电厂烟气Hg排放特征等,指出燃煤电厂实施更严格的烟气Hg排放控制是非常有必要的,且改性活性炭、改性飞灰喷射脱Hg技术将是未来应对更严格Hg排放限值的主流技术。研究结果可为燃煤电厂烟气Hg排放控制提供参考。

Abstract:

Coal-fired power plants is one of the main stationary sources of atmospheric Hg emissions. Based on literature research, source and generation of Hg in flue gas from coal-fired power plants, the existing equipment collaborative Hg removal technology and adsorbent injection Hg removal technology after combustion, the off-line test method of flue gas Hg in coal-fired power plants, the Hg emission characteristics of flue gas from coal-fired power plants before and after the implementation of ultra-low emission were summarized. It is necessary for coal-fired power plants to implement stricter Hg emission control of flue gas. Modified activated carbon and modified fly ash injection Hg removal technology will be the mainstream technology to cope with stricter Hg emission limits in the future. It provides a reference for the Hg emission control of flue gas in coal-fired power plants.
