本文总结了SO2和SO 3释放和捕获的科学知识和实践经验，特别关注富氧燃烧条件对硫排放行为的影响。介绍了在IFK实验性500千瓦大气粉末燃料燃烧装置（KSVA）中获得的有关硫氧化物（SO2/SO 3）排放和捕获行为的结果。实验装置以预干燥的富硫褐煤为原料，在空气和富氧燃料燃烧模式下运行。特别强调了以下问题：·空气和富氧燃料燃烧条件下SO2排放的一般和瞬态行为SO 3·富氧燃料条件下ESP的分离行为·空气和富氧燃料操作的ESP灰分质量的差异
This article summarizes scientific knowledge and practical experiences on the release and capture of SO2and SO3with a special focus on the implications of oxy-fuel combustion conditions on sulphur emission behaviour. Results, obtained at the experimental, 500 kWthatmospheric, pulverized fuel combustion rig (KSVA) of the IFK regarding sulphur oxide (SO2/SO3) emissions and capture behaviour are presented. The experimental plant was operated with pre-dried sulphur rich lignite in air and oxy-fuel combustion mode. The following issues are highlighted in particular:•General and transient behaviour of SO2emissions under air and oxy-fuel combustion conditions SO3•separation behavior of the ESP under oxy-fuel conditions•Differences of ESP ash qualities from air and oxy-fuel operation
