The Selection Of Flue Gas DeSO₂-technology In The Power Plant Of China

Based on the current domestic and international environmental standards and sulphur dioxide emission standards for in-depth and detailed comparative analysis, and in recent years China's total emissions of sulfur dioxide and power generation units of emissions of pollutants and foreign developed countries compared to speed up China's flue gas denitrification technology for the development of the guiding direction. China's current mainstream of the flue gas desulfurization process was introduced, through the process of technical performance and economic performance analysis, using fuzzy comprehensive evaluation of methods, from the environmental performance and economic performance and technical performance of three built coal-fired power plant Flue Gas Desulfurization comprehensive technical and economic evaluation index system, the eight kinds of typical flue gas desulfurization process of the comprehensive evaluation. The results show that at present China's mainstream flue gas desulfurization technology to the merits of the order: wet limestone, water desulfurization, circulating fluidized bed, wet summary, rotary spray drying, wet ammonia, calcium limestone injection by the tail Wetlands activation, electron beam method.
