Conversion of sulfur compounds during co-combustion of sewage sludge and coal mixtures in a O-2/CO2 atmosphere
Sewage sludge and fuel mixts. compounded by addn. of sewage sludge (10-50%) to bituminous coal were combusted in a fluidized bed boiler with O-2 (21-35% by volume) in CO2 atm. The conversion of S to SO2 increased up to 94% with increasing O-2 content in CO2 atm. The conversion of S to SO3 was low (2-6%) and to H2S was negligible (below 0.5%).
