THERMODYNAMIC ANALYSIS OF COMBINED CYCLE POWER PLANTWITH TRANS-CRITICAL CYCLE INTEGERARED WITH SOLAR SYSTEM FOR POWER GENERATION FOR SPACE FOR HEATING AND COOLING

Abstract

Main firmness of my this work to build up a programming code and solving it on computational numerical technique by developing energy balance equation for combine cycle power plant integrated with Trans-critical cycle. A computer programming code has been practiced to imitate a performance under various different conditions under different temperature and pressure circumstances. A study on different cases of Brayton cycle had been analyzed using standard fluids. In this thesis Brayton cycle, Rankine cycle and trans-critical cycle are combined which makes it regenerate cycle and in this thesis the temperature and pressure variations with thermal performance parameters such as thermal’s efficiency, exergy destructions in the various components using trans-critical cycle have been presented. It was found that by increasing condenser temperature of Rankine cycle, the combined cycle efficiency , network are increasing and by increasing the Brayton cycle’s mass flow rate, combined cycle efficiency is decreasing while combined net-work is increasing. Similarly by increasing the exit pressure of pump in the trans-critical cycle, both the combined cycle efficiency & combined net work are decreasing also is decreasing and also by increasing the passage temperature of turbine of trans-critical cycle, the combined cycle efficiency and combined net-work is increasing. On increasing the passage pressure of pump of trans-critical cycle, combined cycle efficiency and combined net work both are increasing.
