【摘要】 介绍氧化镁亚硫酸镁湿法脱硫及其副产物循环利用的工艺。可行性研究表明,这种脱硫工艺脱硫效率高,基础投资和运行成本相对较低,适合离镁矿较近、燃煤硫分低且附近有再生亚硫酸镁化工厂的电厂脱硫,但国内缺少大型电厂的应用业绩。更多还原

【Abstract】 The technology of cyclic utilizing byproducts from wet desulfuration by using magnesium oxidemagnesium sulfite has been presented. Study on feasibility shows that the desulfuration technology of this kind to have high desulfuration efficiency, as well as capital investment and operation cost to be relatively lower. It is suitable for desulfuration in power plant which isn’t far from magnesium mines, has low sulfer content in fuel coal, and has chemical plant for regeneration of magnesium sulfite nearby, but there is short of application achievements in large power plants at home.更多还原
