摘　　要：简述了大气中SO2污染物的排放现状,"十二五"期间的减排目标及粉煤灰的结构特性。介绍了国内外复合型粉煤灰脱硫剂的制备工艺、脱硫工艺及机理、工业应用状况等,论述了燃煤锅炉自身粉煤灰直接用于尾部烟气的干法或半干法脱硫工艺的研究现状。对粉煤灰脱硫剂在烟气脱硫技术方向的应用前景进行了展望。Overview the domestic SO2 emissions status and its reduction targets during the ＂ Twelfth Five- Year Plan＂ period, as well as the structure characteristics of fly ash. Introduce the preparation and desulfurization process, desulfurization mechanism, industrial application of composite fly ash desulfurizer at home and abroad. Investigate the dry or semi dry flue gas desulfurization technologies, which directly use fly ash from coal-fired boiler as desulfurizer. Look forward to the application prospect of fly ash desulfurizer in flue gas desulfurization.
