The following system is a small power generating plantwhich contains a boiler, a superheater, a turbine and a condenser.Describe each part of the system with reference to the equationsrequired in terms of heat transfer and work transfer. The feedwater flows at 1 tonne/hr at 50°C. The output pressure is 6 barwith a dryness fraction is 0.9 and the efficiency of the boiler is75%. The calorific value of the fuel is 38MJ/kg. Determine the fuelflow rate.
The superheater adds 300°C of super heat, determinethe energy input to the superheater assuming no heat loss.
The turbine is 70% efficient and the output steam isat 0.2 bar and 0.8 dryness fraction. Determine the output power ofthe turbine.
