Abstract

In this research, the useful concept of energy and exergy utilization is analyzed, and applied to the boiler system. Energy and exergy flows in a boiler have been shown in this paper. The energy and exergy Efficiency has also been determined with some variations in loads of 300 MW, 275 MW, 250 MW, 200 MW. In the boiler, the highest energy efficiency and exergic efficiency at 300 MW loading were found 73% and 39% respectively. A boiler energy and exergy efficiencies are compared with others workas well. It has been found that the combustion chamber is the major contributor for exergy destruction followed by heat exchanger of a boiler system. The effects of various loads on the boiler are used to see how the performance changes The results showed that the increase in load on the boiler has a positive effect on the exergy efficiency on the cycle as well as the components of the combustion chamber and heat exchanger.
