石灰石-石膏法脱硫烟气pm2.5排放特性
, PP. 1-7
Keywords: 燃煤烟气,wfgd,pm2.5,排放特性
Abstract:
对模拟试验系统和实际燃煤电厂石灰石-石膏法脱硫净烟气中的pm2.5排放特性进行了对比研究。结果表明:模拟系统燃煤细颗粒物数浓度在电称低压冲击器(elpi)可测范围内呈单峰分布,以亚微米级微粒为主,多呈球形结构,主要为难溶于水的硅铝质矿物颗粒。然而,实际电厂燃煤细颗粒物数量浓度呈双峰分布。经过石灰石-石膏湿法烟气脱硫(wfgd)的净烟气中,细颗粒物峰值粒径由脱硫前的0.07μm增至0.15μm,粗颗粒段数量较脱硫前稍有降低,但0.1～0.5μm粒径段颗粒数量浓度反而有所提高;出现少量微米级的块状结晶态细颗粒,ca、s、o元素含量增加。
