Super- Reheat- Rankine Cycle
We are going to add a low pressure turbine (5-6) to the system we just analyzed. Before going into the L-P turbine, the exit steam from the first turbine (3-4) is reheated in the boiler at a constant pressure. Assume both 4 & 6 are at 100% saturated vapor state and the vapor exiting from the H-P turbine (state 4) expands to a lower pressure of 2 MPa (P4=2 MPa) before it is being reheated at a constant pressure to the state 5. Recalculate (a) the thermal efficiency of the system.
