STUDY OF SUB CRITICAL, SUPER CRITICAL AND ULTRA SUPER CRITICAL THERMAL POWER PLANT

Abstract

In this paper the technology study of subcritical, super critical and ultra super critical coal based thermal power
plants have been done in term of electricity production. Power-producers are looking for improve the efficiency of power
plant and also grow concerns about the environmental impacts of power generation without compromising their market
competitiveness. To meet this challenge, this study demonstrates technology up gradation of pulve rized coal fired power
plant in the market. Introduction of these technologies on thermal power plants can changed in Rankine cycle working
temperature and pressure and improve the performance of power plants. The analysis is carried out on 500 MW Subcritical
700 MW super critical and 850 MW ultra super critical thermal power plants. Ultra super critical technology is more
efficient than supercritical technology and subcritical technology in term of performance efficiency and coal consumption.
