Steam power plant, Efficiency, Exergy, Exergoeconomic and levelized costAbstract
A steam power plant was studied using energy, exergy and exergoeconomic analyses. The result of the analysis showed that the major losses occurred in the condenser unit with about 57% of the total fuel lost to the environment while the thermal efficiency of the plant was found to be 38.3%. The exergy destruction in the turbine, heaters, pumps, condenser, boiler and other components were 20.22, 2.40, 4.19, 12.50, 266.81 and 1.52 MW, respectively. The loss in the boiler unit dominated the exergy losses in the plant with about 86.73% of the total exergy destruction. The exergetic efficiency was found to be 36.3%. Furthermore, the exergy and unit exergy cost of the net electrical power produced by the plant were evaluated as US$6713.97/hand US$8.48/GWh, respectively.
