A combined cycle power plant consists of two gas turbines; cach produces a net power of 160 MW, and a 70 MW steam power cycle. The combustion of the fuel in the combustion chamber produces hot gases at 1400°C. The hot gases leaving the gas turbines are used to generate steam through the heat recovery steam generator (Boiler). The hot gases enter the heat recovery steam generator at 880°C and leaves at 660°C. Water enters the isentropic pump as saturated...

Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. The goal of this project is to determine the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows: 1. A natural gas-fired Brayton cycle with mÛ air,Br = 1.25 kg s−1 . (a) Ambient air at 1 bar and 300...
