ANALYSIS OF SHALL AND TUBE HEAT EXCHANGER TO ENHANCE THE PERFORMANCE OF BOILER

This paper present an approach for the optimization of shall and tube heat exchanger for inline tube arrangement. Poor performance for shall and tube heat exchanger is a reason for higher unit heat rate & deterioration for boiler efficiency due to losses of flue gas temperature as a sensible heat loss. Here different value of velocity is used to find out the flow characteristics  on CFD. & it shows that fluid velocity affects the overall heat transfer coefficient
