摘　　要：本文报道了处理量为2000m^3/的喷雾干燥法烟气脱硫试验的结果。化学计量比、烟气绝热饱和温度值、喷雾轮切向速度等因素,对脱硫的影响很大。试验表明,以石灰为吸收剂,当趋近绝热饱和温度值为24.5℃,化学计量比为1.2—1.8时,吸收塔的脱硫率为66—79％。而烟气中SO_2浓度增大时,脱硫率略有下降。The spray dryer absorber flue gas desulfurization is a new technology for SO2 removal. SO2 removal is affected by the stoichiometric ratio. Flue gas out-let temperature approcich to adiabatic saturation temperature and tangential velocity of spray whool etc. This paper introduced the testing results and relation with the main technology factors obtained in a system for treating 2000m3/h flue gas.
