Improvement of Boiler Efficiency in Thermal Power Plants

Boilers in a Thermal power plant are to be operated efficiently to achieve higher plant efficiency in the present day market economy. Many of the boilers operating today are performing at efficiencies that are less than 60 percent. Hence there is huge potential for energy improvements and cost savings leading to higher profits. To achieve this objective, the performance of the boilers is to be assessed and based on which rectification measures are to be incorporated. Because of steep rise in fuel prices and other resources, the optimum use of the resources is very much essential. This can be done by estimating the heat losses occurring in boilers and thereafter finding suitable ways for reduction of losses and the same is dealt by the present paper.
