Abstract
ABSTRACTThis paper presents the exergy and exergoeconomic analysis of a proposed steam reheat power plant powered by the municipal waste of Port Harcourt city in Nigeria, latitude 4°45′ N and longitude 7°00′ E. The projected municipal waste generation of the city for the year 2020 was employed for this work to ascertain the amount of power obtainable via a waste incineration plant, taking into consideration the cost effectiveness of the plant. The thermodynamic analysis of the plant showed that 117 MW could be generated from the projected waste, with plant's first and second law efficiencies of 36.91% and 31.36%, respectively. The plant equipment cost was calculated to be US$326,460,000 with a payback period of about six years. The exergy and exergoeconomic analysis was used to estimate the plant’s unit cost of electricity and evaluate the exergy destruction and cost rates, with respect to the prevalent ambient temperature.
