SO 2 is created during the combustion process when trace amounts of sulphur present in the coal are oxidised by combustion air. Flue gas desulpherisation (FGD) can be accomplished by dry injection of limestone into the ductwork just behind the air pre-heater (50–70% removal) with recovery of the solids in the ESP. For fluidised bed combustion units, the fluidised bed consists primarly of ...
