Özet

This study mainly aimed to determine the performance of the co-combustion of municipal dewatered sewage sludge and natural gas by using actual power plant data for the first time and adding it to published literature. Through a consideration of energy, a thermodynamic analysis of a power plant using municipal sewage sludge was carried out using actual plant data to assess its energetic performance. The fictive molecule C4·13H8·58O2N0·61S0.04 was obtained from the average chemical composition of the dry-based municipal sewage sludge. Energy losses in the plant and its units were determined. The net plant energy efficiencies were found to be 9.095%. The power plant produced 121 Wh of electricity per kg of municipal dewatered sewage sludge. The average value of CO2 emissions from electricity generation was found to be 888 g of CO2/kWhe. Power capacity of 1 MW can eliminate 72,406.7 tonnes of municipal dewatered sewage sludge annually. In an investigated city, 36.93 g of dry sewage sludge was produced per capita per day.
