We have waste incinerator that converts waste fuel into work. The maximum temperature in the boiler is 400oC, the turbine has 100% saturated vapor as the exhaust, and the condenser operates at 75 kPa using steam as the working fluid. Assume the work done by the pump is negligible and the turbine is adiabatic and ideal

Assuming a Rankine cycle,

a) Sketch your cycle on a T-S diagram with appropriate labels. Label the entrance of the condenser as 1, the entrance of the pump as 2, the entrance of the boiler as 3, and the entrance to the turbine as 4.

b)Determine the boiler pressure.

c)What is the work generated?

d)Determine the thermal efficiency of the process.

e)We can increase the thermal efficiency by dropping the condenser temperature but what problems might we encounter if we drop try it to very low temperatures?
