Thermodynamics of energy systems (25 points] dynegy's moss landing power plant in monterey, a natural gas fired plant, used to be the largest generation facility in the state of california with a total installed capacity of approximately 2,000 mw. of the four generators in the facility, the two newer generators are still in operation, but the two older generators were retired in december 2016. the two newer generators (1,500 mw total) are combined cycle (using both the brayton cycle for gas and rankine cycle for steam), and the older two generators (500 mw total) used gas turbines only (the brayton cycle). combined cycles are another way to improve the overall efficiency of a power plant. the rate of energy added during the combustion of fuel when the generator is running at full capacity (not taking into account cycle efficiency) is 2,500 million btu/hr for each old generator. combined cycle natural gas power plants in california have an average annual capacity factor of about 45.7%. a) draw 2 schematics showing the difference between the brayton cycle and combined cycle and label all components. in thermodynamic terms, briefly explain the function of ou each component, including what takes place in each component in terms of heat exchange, work, temperature and pressure.
