PROBLEM: 1. In a gas power plant, liquid normal Butane (n-Butane, C4H10) is used as the fuel in the combustion chamber. The fuel enters the combustion chamber at 25°C and 10 atm at a rate of 0.7 kg/min. The fuel is burned with 180% excess air that is compressed to 10 atm and preheated to 500 K before entering the combustion chamber. The products of the combustion are used as the working fluid in a gas power plant and enter the turbine at 1400 K and 10 atm. The gas leaves the turbine at 800 K and 1 atm. The adiabatic efficiency of the turbine is 80% and the surrounding temperature is 25°C. The combustion process is complete. Draw a schematic diagram of the system and determine: a. The air/fuel ratio. b. The mass flow rate and the volumetric flow rate of air needed for this combustion. c. The rate of heat transfer from the combustion chamber. d. The power output of the turbine. e. The rate of entropy generation (the net rate of change of entropy). f. The rate of irreversibility (exergy destruction) during the whole process. g. Show these processes schematically on a T-s diagram.
