【摘要】 燃煤锅炉烟气脱硫是控制大气污染排放,有效预防酸雨的重要措施.目前国内外研究开发的烟气脱硫技术达200多种,其中湿法烟气脱硫技术因工艺成熟、效率高被燃煤锅炉广泛应用.分析了常用的两种方法,即石膏法脱硫(以废制废)与氨法脱硫(以废制用)的技术工艺现状,并对存在的问题进行了探讨.更多还原

【Abstract】 Flue gas desulfurization of coal-fired boilers is an important method to control air emissions and effectively prevent acid rain.Up to now,there have been more than 200 flue gas desulfurization technologies at home and abroad.Among them,wet flue gas desulfurization technology is widely used in coal-fired boilers due to mature technology and high efficiency.This paper analyzes two commonly used methods,such as gypsum desulfurization(the technical process of desulfurization for waste) and ammonia method(the technical process of desulfurization for use),at the same time the existing problems are analyzed and discussed.更多还原
