5. 4. Application of the ChlorOut concept in a waste wood fired CFB boiler

   University essay from SLU/Dept. of Energy and Technology

   Author : Mårten Carlberg; [2008]
   Keywords : superheater; corrosion; alkali; chlorides; ammonium; sulphate; chlorOut; IACM; potassium; KCl; bio fuels; sulphur;

   Abstract : Boilers converting from sulphur rich fossil fuels to alkali and chlorine rich bio fuels often experience an increased super heater corrosion. This is partly due to the increased formation of KCl during combustion of bio fuels. The problem could, for instance, be handled with a sulphur containing additive to the fuel or to the flue gases.
