Energy and Exergy analysis of a Power Plant and Adoption of OPCAN Power Box for Improving Productivity

Abstract

Most of the electric energy which the world has utilized is generated from coal or gas based on thermal power plants. These power plants have increased the pollution to the maximum extent. In addition to this the population on the world has multiplied as well as their needs. Therefore, there is a scope for the enhancement of the power plants. All these factors have helped to write this research paper. It is based on the thermal power plant located in Ramagundam of Telangana state, India. Power plant performance evaluation is one of the important processes towards the optimization of its performance. Here in this research power plant performance is evaluated based on first law of thermodynamics (energy analysis) and second law of thermodynamics (exergy analysis) and after that organic rankine cycle based opcan power box is introduced in the power plant. By adopting it the performance of the plant is calculated, after that a comparison is made among the efficiencies with energy analysis, exergy analysis and plant efficiency after, before installation of the opcan power box. For all the components the exergy analysis based efficiency is less than efficiency based on energy analysis. The efficiencies of boiler, turbine using energy analysis are more compare with exergy analysis. In addition to this the efficiency of power plant before installation of opcan power box is calculated as 45% and after the installation of the opcan power box it is computed as 46.07%. It indicates that for a 500MW capacity power plant an extra electricity of 6.7MW power is produced without altering the input fuel quantity. The net increase of efficiency of 1.07% indicates that 2-3 % of reduced pollutants.
