燃煤电厂烟气污染物超低排放技术路线的选择

在深入研究燃煤电厂烟尘、SO₂、NO_x等控制技术特点与适用条件的基础上,综合国内大量煤电机组超低排放的成功案例,提出了燃煤电厂超低排放技术路线选择应遵循“因煤制宜,因炉制宜,因地制宜,统筹协同,兼顾发展”的基本原则,辨识出不同煤质、不同炉型、不同机组规模、不同污染控制要求等条件下的最佳可行技术,给出目前应用较多的超低排放典型技术路线,可指导燃煤电厂对超低排放技术路线的选择。

Methodologies on Choosing Appropriate Technical Route for Ultra Low Emission of Flue Gas Pollutants from Coal-Fired Power Plants

Based on the in-depth study on the characteristics and adaptabilities of dust, SO₂ and NO_x control technologies and together in combination with the successful cases of ultra-low emission from domestic coal-fired power plants, the fundamental principles for ultra-low emission technical route selections are proposed, which should be in line with the coal quality, boiler type, local condition, and collaborative development. Then the optimal practical technologies are distinguished under different conditions of the coal quality, boiler type, unit capacity and pollutant control requirements. At last, the most popular and typical technical routes are presented to provide guidance for power plants to make their decisions.
