【摘要】 燃煤电厂有色烟羽不仅污染视觉,还影响周边环境和气候,已引起广泛关注。实现超低排放的电厂,有色烟羽主要表现形态为由雾状水蒸汽形成的白色烟羽和以由SO₃形成的硫酸气溶胶颗粒为主的蓝色烟羽。针对我国采取烟温控制措施的地方白色烟羽治理政策和鼓励SO₃协同脱除的蓝色烟羽治理政策,介绍基于烟气加热、降温冷凝和冷凝再热措施的白色烟羽治理技术以及利用污染物控制设备协同脱除作用和喷射碱性吸收剂的蓝色烟羽治理技术。更多还原

【Abstract】 The colored plume of coal-fired power plants has not only polluted the vision, but also affected the surrounding environment and climate, which has caused widespread concern. For power plants that achieve ultra-low emissions, the main manifestations of colored plumes are white plumes formed by misty water vapor and blue plumes dominated by sulfuric acid aerosol particles formed by SO₃. As the local white plume control policy by flue gas temperature control and the blue control policy encouraging SO₃ synergistic removal in China were concluded, the white plume control technology based on flue gas heating, cooling condensation, condensation and reheating measures and the blue plume control technology using synergistic removal of pollutant control equipment or spraying alkaline absorbent is introduced.更多还原
