Abstract The SO₂ and NO_x emission characteristics during combustion of municipal sludge conditioned with Fenton/CaO and rice husk (RH) blended briquette fuels were studied. The effects of the mixing ratio, temperature and Fenton/CaO dosage on SO₂ and NO_x emission characteristics were analyzed. The results showed that with the increase of RH addition in the sludge mixed fuel, the emission of SO₂ and NO_x gradually decreased, fuel-S conversion rate first decreased and then increased, and fuel-N conversion rate increased continuously. When the temperature gradually increased, the total emissions of SO₂ and NO_x in the combustion process increased correspondingly. Compared with the SO₂ emissions from the unconditioned sludge combustion, the SO₂ generated by the Fenton/CaO conditioned mixed molding fuel combustion was nearly 3.5 times lower; while the NO_x generation was reduced by 1.3 times. The results showed that the mixed combustion of SS2 and 50% RH had the best emission performance at a combustion temperature of 800℃.

Key words： sludge biomass Fenton/CaO emission characteristics SO₂ NO_x
