1 Introduction Low water FGD technologies 5 When coal is combusted in a power plant boiler, the sulphur in the fuel combines with oxygen to form sulphur dioxide (SO 2) and small amounts of sulphur xide (SO 3).Further amounts of SO 3are generated in the selective catalytic reactor, which is widely used for NOx control.
