Abstract

The positive effects of co-combustion with digested sewage sludge on bed agglomeration, deposit composition and initial corrosion have been studied at Chalmers 12 MW CFB-boiler. The trials comprised co-combustion of 4 different sludges and the results were compared with addition of phosphate and sulphate in the cyclone inlet. The base fuel was a mixture of 20 % sorted waste pellets and 80 % bark pellets. Corrosion studies were also carried out at the Haendeloe 75 MW CFB boiler firing 50% household waste and 50% industrial waste. Test rings of chromium rich material (304L and Sanicro 28) were exposed for 24 and about 400 hours with and without cocombustion with digested sewage sludge. Two lab studies have also been carried out; the corrosivity of different phosphates and the effect on bed agglomeration when co-firing 'small amounts' of digested sewage sludge
