Abstract

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.

Key words: coal-fired power, Hg emission, ultra-low emission, Hg removal technology, test method
