Auxiliary power in coal-"red power stations accounts for 7% (500 MW units) to 12% (30 MW units) of the gross generated power at the full plant load. The minimum AP varies between 4)5 and 9)0% for the same capacity range. The excessive power due to factors such as coal quality, excessive steam #ow, i
This paper presents the results of the performance enhancement study on 22 coal "red thermal power stations of capacities 30}500 MW. The oldest units (30 MW) have served for 33 yr and the newer units (500 MW) have been in operation since 7 yr. The turbine e$ciencies are in the range 31)00}41)90% as
This paper provides an analysis of the overall performance of 22 coal-"red power plants. The net overall e$ciency is in the range 19)23}30)69%. The e!ects of ash in coal, contaminants in feed water, leakage, incondensables, etc., have been quanti"ed. Ways of minimizing secondary oil consumption have
