A gas turbine (can assume an ideal Brayton cycle) has a pressure ratio of 10. It is connected to an electric generator with an efficiency of 95% which produces 200MW of electricity. The gas turbine burns natural gas with a heating value of 100,000 btu/therm. The waste heat from the gas turbine is used to generate steam in an ideal Rankine cycle. The efficiency of the Rankine cycle is 30%. The turbine of the Rankine cycle is attached to an electric generator with an efficiency of 95%. What electric output would you estimate for this electric generator? This system is called a combined cycle where you combine a gas turbine with a Rankine cycle (called the bottoming cycle in this case) to achieve an overall higher efficiency.
