Performance Analysis of Supercritical Power Plant using Imported Coal and Enhancement of Plant Availability by Retrofitting of Pulverizer

Abstract

World energy demand is increasing relentlessly. The total global energy demand in 2030 is projected to be 50 60% above the current rate of energy consumption (IEA, 2008). Existing developed economies and fast) growing ones like India and China rely heavily on fossil fuels as a source of energy. Coal is still a key element in the energy mix for the world s leading economies, and around 30% of all CO2 emissions come from the combustion of fossil fuels for electricity generation (IEA, 2008). Therefore, there is a need for clean coal technology to reduce the negative effect of the combustion. For the combustion researchers coal fired thermal power plants of higher performance efficiency and lower pollutants emission is a major issue for analysis of advanced technology. newlineApplication of Super-critical and Ultra-supercritical technology for steam generation to boilers fired with pulverized coal is the best technology at present for the clean power generation. newlineThe present work details a performance analysis of super critical power plant in terms of its auxiliaries as Boiler, Turbine and Generator performance. newlineThe particular area of focus is mill (pulveriser) fire, the supercritical units which are working on imported coal has experienced this problem newlineThe outcome of this research work provides possible solution in-terms of newline- Mill dynamic temperature responses over wide range of coal quality using the mill simulation newlinemodel. newline- Performance can be improved by appropriate control strategy which meets mill temperature newlinecontrol and improve the availability of mill and over all plant. newline
