摘　　要：国华台山发电有限公司(台山电厂)在满足锅炉正常运行的前提下,通过抽取部分热二次风注入脱硫后净烟气,提升排烟温度,以减少或消除"石膏雨"。通过热力学计算,对比二次风温度、空气预热器出口烟气温度、屏式过热器入口烟气温度等参数在不同工况时的变化。比较实施本方案与加装烟气热交换器(GGH)方案的差异。结果表明,采用热二次风加热脱硫后净烟气具有投资小、维护费用低、运行可靠性高等优点,但锅炉热效率略有降低。Under premise of satisfying boiler operation in Taishan Power Plant, the exhaust flue gas temperature has been enhanced through extracting a part of hot secondary air to inject into the cleaned flue gas after desulfurization, so as to reduce or eliminate the ＂ gypsum rain＂. Through thermodynamics calculation, and comparing variation of parameters, such as the temperature of secondary air, the temperature of outlet flue gas from air preheater, and the temperature of inlet flue gas into platen superheater, etc. , a scheme of additionally installing the gas- gas heater（gghy）has been put forward.
