Improving the Thermal Efficiency of the Power Plant

Design a steam power cycle that can achieve a cycle efficiency of at least 40 percent underconditions that all turbines have isentropic efficiencies of 80 percent and all pumps haveisentropic efficiencies of 65 percent. Prepare an engineering report describing your design.Your design should include the following,a. Discussions of various cycles attempted to meet the goal as well as the positive andnegative aspects of your design.b. System figures and T-s diagrams with labelled states and temperature, pressure,enthalpy and entropy information for your design.c. Show at least one sample calculation for each new system implemented.d. If you are using programming language for the generation of more data, you areexpected to attach the code or programme as an appendix. Programmes such asMATLAB, EXCEL and EES (Engineering Equation Solver) might be used for thispurpose.
Early commercial vapor power plants operated with turbine inlet conditions of about 12 barand 200oC. Plants are under development today that can operate at over 34 MPa, with turbineinlet temperatures of 650oC or higher. How have steam generator or turbine designs changedover the years to allow for such increases in pressure and temperature? Discuss.
