Need plots 1 and 3.

Conduct a parametric evaluation of your system varying the boiler saturation temperature from 150 degree C to 350 degree C. As you vary the boiler temperature, make sure that the hot air coming out of the boiler remains 50 degree C higher than the boiler saturation temperature. Assume: Dead state is T_0 = 20 degree C and P_0 = 100 kPa Develop the following plots: Thermal efficiency versus boiler saturation temperature Fuel-to-electric efficiency versus boiler saturation temperature Rate of exergy destruction in boiler versus boiler saturation temperature Rate of exergy destruction in the HP and LP turbine (two plots) versus boiler saturation

Solution

heat engines transfor thermal energy or heat qn into mechanical energy or work Wout. they cananot do this task perfectly so some of the input heat energy is not converted into work, but s dissipated as waste heat Qout into the environment

Qin=Wout+Qout

the thermal efficiency of a heat engine is the percentage of heat energy that is transformed into work
