摘要: Sewage sludge can be disposed of by fermentation, incineration or gasification. Conversion the resulting biogas, combustion heat gasification gas into electricity is often employed. Since sewage cannot fermented completely and due to significant requirements for drying it in plant before gasifier, electrical output all cases very low. Consequently, this work seeks investigate a combination fermentation which dried waste converted gasifier. With aim combining these two biomass conversion processes with power generation an efficient manner, hybrid system consisting SOFC turbine investigated. This biogas gasifier has advantage that used as source waste. Another combined SOFC. As steam from internal reforming methane out at anode SOFC, complexity reduced efficiency increased. A configuration including pressurized process was identified most terms output.
