The following system is a small power generating plant which contains a boiler, a superheater, a turbine and a condenser. Describe each part of the system with reference to the equations required in terms of heat transfer and work transfer. The feed water flows at 1 tonne/hr at 50°C. The output pressure is 6 bar with a dryness fraction is 0.9 and the efficiency of the boiler is 75%. The calorific value of the fuel is 38MJ/kg. Determine the fuel flow rate.

The superheater adds 300°C of super heat, determine the energy input to the superheater assuming no heat loss.

The turbine is 70% efficient and the output steam is at 0.2 bar and 0.8 dryness fraction. Determine the output power of the turbine.

In the boiler of a power plant are tubes through which water flows as it is brought from 0.8 MPa, 150°C to 240°C at essentially constant pressure. The total mass flow rate of the water is 100 kg/s. Combustion gases passing over the tubes cool from 1067 to 277 °C at essentially constant pressure. The combustion gases can be modeled as air as an ideal gas. There is no significant heat transfer from the boiler to its surroundings. Assuming steady...
