Effectiveness Improvement of Shell And Tube Type Heat Exchanger

Generally, 35-40% of the heat exchangers used in industries are shell and tube heat exchanger. Here in this project the shell and tube type of heat exchanger is designed an experiment on it is conducted. There are problems like scaling, fouling, welding defects and maintenance cost. In this experiment, design of shell and tube type heat exchanger baffle is changed. Considering this design as the basis, effectiveness of shell and tube type heat exchanger is measured. The performance in terms of effectiveness is firstly measured for normal flat baf¬fle having 3:2 cutting ratio. Then performance in terms of effectiveness is measured for helical baffle. After measuring the performance for both types of baffle, results of both experiments are compared. Also the turbulence gained due to helical baffle helps to reduce the fouling effect in the heat exchanger.
