Abstract

In India, coal is the dominant source of energy generation. Efficiency of any conventional coal fired unit ranges from 34-38%. This paper presents the efficiency calculation of boiler, turbine and condenser of a 210 MW unit. The study focuses on evaluation of various parameters like dry flue gas loss, wet flue gas loss, moisture in fuel and hydrogen, condenser back pressure, turbine cylinder efficiency, soot formation, etc. and some optimization techniques are mentioned to minimize the same. The benefits of these techniques are considerable fuel saving, emission reduction, heat rate improvement, cost minimization, increased equipment life cycle, etc. Cost analysis through heat rate
deviation has been done to determine annual fuel savings. Lastly various critical parameters are mentioned for further improvement of plant performance

Keywords: Coal fired power plant, rankine cycle, boiler efficiency, turbine efficiency, condenser efficiency, heat rate

Article published in International Journal of Current Engineering and Technology, Vol.7, No.1 (Feb-2017)
