Abstract

The energy and exergy analyses especially of  boiler of 50 MW unit of lakhra power is demonstrated through EES software  in this research paper because of its  consistent, persistence and recurring failure even its minor failure renders whole power plant to  remain shut down for indefinite period of time till its rectification, repairing, maintenance and replacing. However, the chief parts of boiler in the plant are fluidized bed combustion chamber, super heater, economizer and air preheater which are aimed at increasing overall efficiency and optimizing performance by proper utilizing supposed-to-be wastage like flue gas and its high temperature heat and energy potential. Through energy analysis the energy loss along with the first law efficiency of the parts have been computed and calculated which shows quantitative loss while for qualitative loss the exergy method has been employed to figure out second law efficiency of components of boiler, generation of entropy, irreversibility and destruction. Through the investigation it was witnessed that the most destructive parts of boiler is the combustor where uncontrolled chemical reactions and maximum loss and destruction, due to heat loss and radiation losses, take place where energy loss is 90% and exergy destruction is 55% succeeded by super heater where 5% energy loss occurs and 36% exergy destruction happens. The highest optimized part of the boiler is air preheater that has 78% and 79% energy and exergy efficiency respectively.
