Enhancing energy efficiency of auxiliary power system in a 210 MW coal fired power plant through energy efficiency

This paper describes the results of energy conservation measures in various thermal power plants spread over the country. Energy savings in various major auxiliaries are summarized here with improved performance. Staggering of auxiliary loads, reduction in hydrodynamic resistance of pipes and ducts, adoption of new energy efficient technologies, efficient control techniques, reduction in furnace ingress and monitoring of coal size at mill inlets will lead to substantial amount of energy savings. The energy conservation schemes are economically attractive with a break even period of 1 to 5 years.
