TAILIEUCHUNG - Componentwise thermodynamic analysis of thermal power plant by designed software

Thermodynamic/exergy analysis is performed at different inlet pressure conditions of steam and identified conditions at which the performance of the plant is best. This software also helps to develop correction factor curves for power and heat rate at different inlet pressure conditions. | Journal of Automation and Control Engineering Vol. 4, No. 4, August 2016 Componentwise Thermodynamic Analysis of Thermal Power Plant by Designed Software Ankur Geete Mechanical Engineering Department, S. D. Bansal College of Technology, Indore, Madhya Pradesh, India Email: ankur_geete@ Abstract—This research work is based on 120MW thermal power plant which has five major components. The components are–steam turbine, condenser, feed water heaters and boiler. Each component is having its own importance and it effects the performance of power plant. In this research work component wise thermodynamic/exergy analysis is done. For analysis, more general software is designed. By this software, thermodynamic/exergy analysis is performed at different inlet pressure conditions of steam and identified conditions at which the performance of the plant is best. This software also helps to develop correction factor curves for power and heat rate at different inlet pressure conditions. that, steam is reheated and then enters into IP turbine. In IP turbine, steam is expanded and some amount of steam is extracted from two extraction points for feed water heater number 5 and deaerator respectively. After expansion in IP turbine, steam is again extracted for feed water heater 3. Then finally steam enters into LP turbine where it is expanded and steam is again extracted from two extraction points for feed water heater number 2 and feed water heater number 1 respectively. Then wet steam is condensed and converted into water in condenser. After heating in different feed water heaters, water enters again into the boiler with the help of feed water pump [1]. Some important terms which are used during analysis of power plant–(1) Correction factor–it is the ratio of designed output to actual output. Example–correction factor for power is the ratio of designed power to actual power output (net power) [1]. (2) Flow function-it shows the relation between mass flow rate, specific .
