A conventional coal-fired power plant produces electricity by the burning of coal and air in a steam generator, where it heats water to produce high pressure and high temperature steam. The steam flows through a series of steam turbines which spin an electrical generator to produce electricity. Ultra supercritical (USC) steam power plants meet notably the requirements for high efficiencies to reduce both fuel costs and emissions as well as for a reliable supply of electric energyTechnologies for removing CO2 from the exhaust gas of coal-fired steam power plants are still under development. 1. INTRODUCTION. This coal-fired power plant (XYZ Company, name disguised) provides the electricity to the Electricity Generating- The amount of fuel energy input needed to produce electrical energy output (heat rate, kJ/kWh) is the key factor to measure the overall efficiency of the plant. Energy efficiency of a power plant.Coal fired power plant operates on modified Rankine cycle. Its efficiency is decided by parameters of this cycle. Fossil fuel-fired power plants today supply over 65 of electricity in the world, with coal-fired power plants accounting for about 40 of the total.There are two main ways to reduce the electricity industrys carbon footprint: improving energy efficiency or availability of the plant. l The present worldwide average energy efficiency of coal power plants is around 33 per cent, but even the newest coal-fired plants do not reachl If Europe replaced its old power plants with high-energy efficient coal -fired power plants, CO2 emissions could drop by around 25-30 per cent.
