Abstract

Due to the growing demand for generating and the depletion of basic resources, power plants with larger capacity and higher efficiency are becoming increasingly necessary. In this context, Governments and private sectors are going to invest huge resources to construct power plants with super-critical units working on Indian as well as imported coal (Indonesian & South African). Supercritical technology is always embraced all over the world, and India is no exception, with many future facilities being based on this technology. CCS does not raise the environmental effect categories of ozone depletion or ionization radiation. These increases are primarily due to the coal supply chain, energy penalty, waste disposal, direct emissions, and capture technology infrastructure. The advantages of the super-critical cycle are a lower heat rate, low fuel burn rate, lower emission rate, and improved load response. Now, the point that needs to be addressed is how these advanced technology units perform in Indian conditions - their performance, efficiency, availability, environmental and other issues. In this paper, an attempt is made to compare the efficiency of the supercritical boiler of capacity 660MW using Indian as well as imported coal.
