Performance Enhancement Techniques for Boilers

Abstract

The major part of power generation in the country is from coal based power plants. The most important factor in deciding the overall performance of energy conversion in a coal fired power plant is the boiler efficiency. Analysis on performance of operating boilers in a certain 210 MW plants was made to check their performance levels. Boilers at these power plants have been found to be operating on the lower performance levels than desired. This is primarily due to improper maintenance of certain important operating parameters at the specified values. Boiler performance could be enhanced resulting in considerable savings in fuel and power, and reduction in emissions by monitoring, controlling and maintaining the operating parameters properly which is discussed in this paper.
