Question

a steam power plant operating on the simple ideal rankine cycle is considered. the heat input into the cycle is 2728 kj/kg, and the heat output is 2018 kj/kg. determine the thermal efficiency of this cycle.

Answer 1

The average temperature at which heat is fed to the cycle is raised, increasing the Rankine cycle's thermal efficiency. lowering the typical temperature at which the cycle rejects heat.

Power plants that employ coal or nuclear energy frequently use the Rankine cycle, also known as the Rankine Vapor Cycle. A fuel is used in this mechanism to generate heat in a boiler, turning water into steam that expands via a turbine to provide useful work. The Rankine cycle's efficiency is lower than that of a Carnot cycle operating between the same maximum and minimum temperatures because the mean temperature at which heat is provided is lower than the maximum temperature,
