The objective of the current work is to gain understanding of the Heat Recovery Steam Generators (HRSGs), specifically the solid/serrated finned tubes used in the economizer section of the HRSG and aid the experiments conducted through mathematical modelling and give economic/environmental context to the whole project. A clear explanation of the formulas used by the industry to calculate the performance of a staggered tube bundle in HRVG has been given and the formulas have been converted into metric system to simplify & adhere to current academic/international standards. The results from the experiments have been validated using the current correlations as the standard. Finally, a new design application, called Heat Recovery Vapor Generator (HRVG), which uses a refrigerant instead of water is proposed, to have a faster path to market. The economic, environmental, and performance advantages have been presented for a better understanding of the potential of this new design.
