Heat Rate Calculation and Its Optimisation for 2x 600 Mw Thermal Power Stations and Reduction of Co2 Emission in Flue Gas

Abstract

In the present power system scenario major portion of the Electricity is produced from Thermal Power stations. Even though there is a penetration of renewable energy sources, the base load operation of power generation depends on the Thermal power generation. The Thermal Power plants also meets the demands when the Renewable energy sources are letting down supplying power to the Grid, and to operate in a safe mode region during the Demands. Under these scenario the thermal efficiency of the coal based Thermal power station is based on the reduction in heat rate. The heat rate of the thermal power station, otherwise the ratio of the KWh generated as output to the Kilo Calories given as input to the power plant. The reduction in heat rate and improving the Thermal power station efficiency reduces the CO? emission .The study of the Thermal power station 2X600 mw by collecting the numerical values of regenerative cycle efficiency of the power plant major equipment Steam generator and turbine with steam cycle Boiler also the Turbine with steam cycle. The study also focuses on Thermodynamic steam to power cycle. The parameters of the Thermal Power station is optimized .The study focuses light on the steam cycle thermal efficiency, fuel burnt with unit in Kwh generated , CO? emission, the furnace temperature at the firing zone in the boiler and temperatures the flue gas path. By conducting the analysis of 2X600 MW coal powered Thermal power Station, the influence of the operating parameters in the Heat rate of the plant and its CO? emission is realized .The outcome of the study reveals the optimized parameters and procedures for the power station is derived and thus reducing the co? emission.
