对１００ＭＷｅ（含１００ＭＷｅ）以上的燃煤电站的烟气脱硫工艺（ＦＧＤ）进行了调研．总计调研了２３９个项目计３４６台机组，１３４０８１ＭＷｅ．内容有电站名称、地点和容量、煤种类型与含硫量，同时包括了脱硫设备制造厂家、烟气流量、脱硫效率和有无烟气脱硫的副产品处理设施等．统计表按脱硫工艺的类型分类，统计结果为１１种抛弃工艺和４种回收工艺在电站中均有应用．统计表中也给出了每种工艺占总计容量的百分比．统计表明，各种脱硫工艺按设备容量所占比例按下列次序递减：石灰石／石膏洗涤工艺、传统石灰石洗涤工艺、石灰洗涤工艺、石灰喷雾干燥工艺、石灰／石膏洗涤工艺、加添加剂的石灰洗涤工艺、钠碱洗涤工艺、韦尔曼—路德工艺、氧化镁工艺、双碱洗涤工艺、石灰—石灰右／石膏工艺、加添加剂／石膏的石灰洗涤工艺、苏达粉喷雾干燥和活性炭吸收工艺．这次调研结果表明了燃煤电厂选择脱硫工艺的趋势．
The flue gas desulfurization (FGD) process for a 100 MWe (100 MWe) coal-fired power plant was investigated. A total of 239 projects surveyed 346 units, 134081MWe. The content includes the name, location and capacity of power station, coal type and sulfur content, as well as the desulfurization equipment manufacturers, flue gas flow, desulfurization efficiency and flue gas desulfurization by-product processing facilities. The statistical tables are classified according to the type of desulfurization process, and the statistical results are that 11 kinds of disposal processes and 4 kinds of recovery processes are applied in the power station. The statistics also show the percentage of total capacity of each process. The statistics show that the desulfurization process is decreasing according to the proportion of equipment capacity in the following order: limestone / gypsum washing process, traditional limestone washing process, lime washing process, lime spray drying process, lime / gypsum washing process, additive lime washing process , Sodium-alkaline washing process, Werman-Luther process, magnesia process, double base washing process, lime-lime right / gypsum process, lime washing process with additive / gypsum, spray drying and activated carbon absorption process of Sud powder. The findings of this study show that the choice of coal-fired power plant desulfurization process trends.
