【摘要】：近年来,我国大气复合污染问题日益突出,燃煤是造成大气污染的主要原因之一,我国电力行业耗煤量约占全国耗煤总量的一半,实现燃煤电厂烟气污染物高效控制是重中之重。本文介绍了我国煤炭清洁发电实现超低排放的最新进展及未来发展前景。通过理论研究、技术研发及集成应用,形成了符合我国国情的燃煤烟气污染物超低排放技术路线,建立了超低排放清洁环保岛,实现了污染物排放优于天然气机组排放标准限值,为我国大气污染防治特别是高用能密度区域的污染物减排提供了一条重要出路。研究综述了近年来我国超低排放技术的示范应用情况,通过费效分析表明超低排放可实现污染物大幅度减排,具有良好的环境、经济和社会效益。未来,我国燃煤电厂还将进一步发展烟气污染物深度脱除技术及二氧化碳捕集技术,最终实现燃煤烟气污染物的近零排放,为建设全世界最清洁的燃煤电厂奠定坚实的技术基础。
[Abstract]:In recent years, the problem of complex atmospheric pollution in China has become increasingly prominent. Coal burning is one of the main causes of air pollution, and the coal consumption of power industry in China accounts for about half of the total coal consumption in China. It is very important to realize the efficient control of flue gas pollutants in coal-fired power plants. This paper introduces the latest progress and future development of coal clean power generation in China. Through theoretical research, technology development and integrated application, the ultra-low emission technical route of coal-fired flue gas pollutants was formed, and the ultra-low emission clean and environmental protection island was established. The emission of pollutants is better than the emission standard limit of natural gas units, which provides an important way for the prevention and control of air pollution, especially for the emission reduction of pollutants in high-energy density areas in China. This paper summarizes the demonstration and application of ultra-low emission technology in China in recent years. The results of cost-effect analysis show that ultra-low emission can greatly reduce the emission of pollutants, and has good environmental, economic and social benefits. In the future, coal-fired power plants in China will further develop the technology of deep removal of flue gas pollutants and carbon dioxide capture technology, which will eventually achieve near-zero emissions of pollutants from coal-fired flue gas. For the construction of the world's cleanest coal-fired power plant to lay a solid technical foundation.
