After studying literatures mentioned in the literature review chapter, it is understood that there are some gaps in design of shell and tube air preheater. The main aim of the project investigation is to modify the design of air preheater, mentioned in Das et al. [40] to increase its heat transfer coefficient and hence improving its performance and efficiency. The tubular preheater ducts for cold and hot air require more space and structural supports than a rotating preheater design. Further, due to dust-laden abrasive flue gases, the tubes outside the ducting wear out faster on the side facing the gas current. Many advances have been made to eliminate this problem such as the use of ceramic and hardened steel. This project also contains the method for calculating boiler efficiency using indirect method and reduce the losses in air preheater by changing the tube diameter of air preheater in ANSYS Fluent (CFD) software and validating its results from literature Das et al. [40].
