The Sulphur Mass Balance in Oxy-Fuel Combustion of Lignite
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2009

This work presents an experimental study of the sulphur chemistry in oxy-fuel combustion of pulverized lignite. It has been observed that the emission of sulphur dioxide (SO2) by unit energy supplied is lower in oxy-fuel combustion than in air combustion [1-5] but the reason for this is not clear. In order to validate previous work and to clarify this difference the present work compares the amount of emitted SO2 in air and oxy-fuel combustion (wet and dry flue-gas recycle). Furthermore, the amounts of sulphur in the ash and in the water of the flue-gas condenser were determined to make a mass balance and to verify the measured amount of SO2 in the flue gas.
