Computerized Analysis of Superheated Rankine Cycle
Keywords:
Rankine cycle, thermal efficiency, specific steam consumptionAbstract
Thermodynamic property equations obtained from the literature have been used to simulate
the performance of a superheated Rankine cycle, with water as the working fluid. The
equations were embedded in a computer program, where the inputs are condenser
pressure, boiler pressure, turbine inlet temperature, and isentropic efficiency of the turbine.
The program outputs are the heat supply at the boiler, network output, thermal efficiency
and specific steam consumption. A case study demonstrates the effects of the condenser
pressure, boiler pressure, and turbine inlet temperature on the cycle performance. The
program outputs replicate the well-known facts, where thermal efficiency increases with a
decrease in condenser pressure and it increases with an increase in the turbine inlet
temperature.
