介绍了燃煤电厂SO₂超低排放主流技术路线,并分析研究了各种技术路线的适用性。现场实际工程监测结果表明,各技术路线均满足"超低排放"要求,为燃煤电厂选择"超低排放"脱硫技术提供借鉴。

China has always faced huge challenges in controlling air pollution due to major share of coal in energy consumption.In order to meet the requirement of ultra-low emission,coal-fired power plants need to upgrade or renovate their limestone-gypsum desulfurization system.Mainstream technical routes for ultra-low SO₂ emission in coal-fired power plants are introduced,and their applicability is analyzed and compared.It is declared through application in actual engineering cases that all of the technical routes can meet the requirements of ultra-low SO₂ emission in coal-fired power plants,which provides guidance for coal-fired power plants.
