Steam boiler with superheat coil. The boiler is fueled by C7.6H2.2 fuel with LHV of 9 MJ/kg and 6.1 excess air supply. The boiler is connected to multistage steam turbines with total electrical power output target of 3.2 MW. Assume maximum steam temperature and pressure to be 500°C, and 100 bar, respectively, and assume ideal turbines operation. The steam exits the turbine at 0.9 steam quality (x). (1) Write the molar reaction for actual air flow (2) Calculate the stoichiometric and actual air fuel ratios. (3) Calculate the condenser pressure. (4) Calculate the greenhouse (CO2) emissions. (5) Calculate the overall power plant efficiency.
