Therefore, understanding the coal-fired boiler flue gas desulfurization technology in the process of air pollution control is extremely important. This paper mainly introduces the technology of limestone - gypsum wet flue gas desulfurization technology in the monly used in flue gas desulfurization . Key words : Flue gas , desulphurization , air pollution , technology, 1. air pollution and its harm The chart is the main air pollution and its source: Serial number project Also the prototype (coal) Oxidized (car exhaust) 1 The main source of pollution The factory, family life, heating coal emissions SO 2、 NO ×、 HC × Automobile exhaust, fuel oil pollutant emissions are mainly NO ×、 HC × 2 Pollution One time, two times SO2, CO2 mixed gas pollutants, CO parti
