This article summarizes scientific knowledge and practical experiences on the release and capture of SO2 and SO3 with a special focus on the implications of oxy-fuel combustion conditions on sulphur emission behaviour. Results, obtained at the experimental, 500 kWth atmospheric, 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 SO2 emissions 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 (C) 2013 The Authors.
