The cogenerating power plant shown in Problem 9.80 burns 170 kg/s air with natural gas, CH 4
Question:
The cogenerating power plant shown in Problem 9.80 burns 170 kg/s air with natural gas, CH4. The setup is shown in Fig. P13.205, where a fraction of the air flow out of the compressor with pressure ratio 15.8:1 is used to preheat the feedwater in the steam cycle. The fuel flowrate is 3.2 kg/s. Analyze the system, determining the total heat transfer to the steam cycle from the turbine exhaust gases, the heat transfer in the preheater, and the gas turbine inlet temperature.
