| Abstract | ||
| This paper deals with parametric of thermodynamic analysis of a gas power plant has 165.1 MW rated power capacity. This plant established as a gas power plant in Mosrata, (Libya) to feed an iron and steel factory. The thermodynamic analysis energy and exergy analysis indicate how much power has been rejected in the exhaust gases in case of gas power plant only. In order to enhance the exergy and energy efficiencies, this study propose a steam unit as a (combined power plant). The gas plant was designed to work under different part load of 0.2, 0.4, 0.6, 0.8, and at full load. Then, the thermodynamic energy and exergy analysis of the plant has been carried out. The energy and exergy efficiencies were calculated according to the first and the second laws of thermodynamics. It is concluded that the overall thermal efficiency can be improved by 9.835% and the exergy can be enhanced by 9.34% at full load. | ||
