| This paper presents the results of a research into the feasibility of recovering waste heat and determining design parameters of a recovery boiler for a set of medium-speed diesel generators with a capacity of 7 MW (the nominal capacity of all units is 42 MW, which would be a study on a unit). And is used to generate electricity. The main purpose of this study is to design a thermal waste recovery system for motors and to utilize geothermal technology for the power plant cooling system. The maximum theoretical potential of power generation is estimated at about 22 MW, and the pinch analysis model enables this potential to reach 80%. In this paper, the exergy performance and unit economic analysis are also performed for the optimum stage and the results are investigated at different minimum temperature and different pinch points. Finally, a geothermal cooling system is designed to control the thermal pollution of the exhaust gases and the water consumption of the system. Also, combining the power plant cycle has a positive effect on the exergy and unit energy efficiency (17and 14.1%) and increases the power generation of the power plant by 19 MW. |
