Performance Analysis From The Efficiency Estimation of Coal Fired Boiler

Coal fired Boiler is one of the most important components for any Thermal Power Plant. The prominent Performance parameter of a boiler is “Boiler Efficiency”. Boiler Efficiency affects the overall performance of the electricity generation process and as well as plant economy. Boiler efficiency is affected by many factors. It reduces with time, due to various heat losses such as loss due to unburnt carbon in waste, loss due to dry flue gas, loss due to moisture in fuel, loss due to radiation, loss due to blow down, and loss due to burning hydrogen, etc.. Boiler efficiency tests help us to calculate deviations of boiler efficiency from the design value and identify areas for improvement. The current paper puts forward an effective methodology for the efficiency estimation of a coal fired boiler, comparison with its design value and enlists some of the factors that affect the performance of a boiler. This study will help to increase overall boiler efficiency and as a result, annual monetary savings of the thermal power plant.
