Abstract: Indian energy sector mainly depends on the fossil fuel based power plants especially coal based power plants. The performance of coal based power plants in India is poor compared to other advanced countries due to prolonged use of smaller size power plants who have served more than 35 – 40 year with refurbishments and poor coal quality. The auxiliary power in thermal power plant plays a major role in performance of plants because the average auxiliary power consumption varies between 7.5 – 14.3% of plant load depending on the plant size. In this paper the avenues for improving the power plant performance by implementing the energy conservation measures like reducing the hydrodynamic resistance in flue gas & air ducts through clearing the debris, control of illegal furnace ingress, efficient control techniques, cleaning air baskets in air preheaters, operational optimization, variable frequency drives, etc. that reduces the energy consumption by 5.5 to 6.5 MU/year which reduces the overall auxiliary power by 0.5% of plant load.
Keywords: Auxiliary Power, Energy Conservation, Induced Draft Fans, Forced Draft Fans, Primary Air Fans, Air Pre-Heaters.
