چکیده: Abstract: Due to the high importance of electrical energy and the high demand for electricity, as well as the growth of power and fuel production costs, it has caused more research to be done for the development and progress of power generation cycles. With the introduction of gas turbine, an important step was taken in power generation, which in the early stages, its efficiency was significantly lower than that of steam turbine. Over time, the efficiency of the gas turbine cycle increased by providing different methods. The Maisotsenko Gas Turbine Cycle (M-Cycle) by relying on the principles of the Brayton cycle and adding a special mass and heat exchanger to it, has been able to successfully increase the efficiency of the gas turbine cycle. In this cycle, by adding steam to the compressed air flow after the compressor, the enthalpy of the flow increases due to the high heat capacity of water. Also, due to the injection of steam into the stream, the emission of NOx pollutants decreases. In the Maisotsenko gas turbine cycle, waste heat from the turbine exhaust is used to inject steam into the flow, which is one of the reasons for increasing efficiency in this cycle. In this research, the Maisotsenko gas turbine cycle (M-Cycle) is studied as a more efficient cycle than the simple Brayton cycle and is environmentally friendly. On the other hand, by combining the simple Brayton cycle and the Maisotsenko mass and heat exchanger, reusing the exhaust heat, injecting steam into the flow and using a two-stage compressor with an intermediate cooler, fuel consumption and Nox environmental pollutants are reduced and the overall efficiency of the system is increased, which can be very interesting considering the mentioned benefits
