Analysis Of Rankine Cycle And Its Utility In Thermal Power Plant - A Theoretical Approach
Most of the thermal power plants work according to Rankin cycle with superheat, reheat and
regeneration. Thermodynamic analysis of Rankin cycle has been undertaken to enhance the efficiency and
reliability of steam power plant. However, electricity is being produced by some other sources like hydro power,
solar power, wind power, geothermal power etc. but absolute majority of electricity production throughout the
world is from steam power plant. Based on a project activity and local power plant experience some key
observation has made and is presented in this paper. A comparative study between Rankin cycle and Carnot cycle
efficiency has been analyzed. The study on coal-fired power plant analysis gives a better insight into the cycle
operation with various system components and components required for operation. Factors affecting efficiency of
Rankin cycle have been identified and analyzed for improved working of thermal power plant. Some recent
developments to enhance the efficiency of Rankin cycle have been analyzed.
