Abstract
The results from the Energy audit of KO- THAGUDEM Thermal power station, Andhra Pradesh has been presented in this paper. The scope of any energy audit in a thermal power plant should include the study of the coal flow, air and flue gas flow, excess air factors and oxygen in the flue gas; study of the heat transfer, effectiveness, proportioning of heat and pressure drop in the heat - exchangers of the water - steam circuit; study of the auxiliary power consumption; the overall performance evaluation such as the gross and the net overall efficiencies, boiler efficiency, boiler feed pump efficiency, air compressor efficiency, evaporation losses and blow down losses of cooling tower etc. Results from such a study at a 500 MW power plant are presented in this report. A detailed analysis of the effect of the fuel on the boiler efficiency, the dry and the wet flue gas loss, combustion characteristics, the start - up and the shut - down losses, the radiation losses and the heat losses due to hydrogen in fuel, moistu re in fuel, carbon monoxide in fuel are explained. Factors leading to the deterioration of the boiler efficiency by direct method and indirect method and evaporation losses and blow down losses of cooling tower are also presented.
