Abstract

The combustion and emission characteristics of sludge, biomass (rice husk, peanut husk, pine sawdust) and their blends were studied by non-isothermal thermogravimetry, tube oven method and SEM. The results showed that the combustion process of sludge, biomass and their blends could be divided into three stages: the evaporation of water, the release and combustion of volatile, combustion of char. Combustion characteristics of 80% biomass +20% sludge were improved compared with the theoretical value. NO_x and SO₂ emission of 80% biomass +20% sludge was lower than that of sludge combustion. There was synergistic effect between sludge/biomass combustion. Comparing combustion and emission characteristics comprehensively, the mixed fuels of 80% biomass +20% sludge could promote combustion and reduce emissions, which was a better method to treat municipal sludge.
