I discussed a master's thesis in the College of Engineering at the University of Basrah, and it included the thesis entitled (Thermal and Economic Impact of Using Waste Heat in Gas Turbine Units in Power Generation and Refrigeration). Characterized by the ocean temperature, the Najibiya gas station was chosen as a case study. The station consists of four units with a production capacity of 125 megawatts per unit for the student Hossam Taleb Khrebesh. The thesis aims to study the thermal and economic impact of waste heat from gas power stations to the external environment at different temperatures and to study the improvement in thermal performance It is economical to connect heat recovery systems with gas power plants in addition
To determine the economic losses of waste heat associated with waste gases and different temperatures from the surrounding environment. The results showed that the increase in the temperature of the external environment leads to a decrease in the rate of the incoming air and thus a decrease in the output power. Analysis of the available energy (the elixir G) The largest amount of energy damage occurs in the combustion chamber 33% of the amount of available energy supplied in the combustion chamber For the combined (gas - steam) power plant, the percentage increase in thermal efficiency is about 46.4% The results indicate that the combined power plant is very important to increase the electric power
