Abstract
The exhaust gas from the boiler in the laundry industry can reach more than 300 °C. It is the potential energy that can be converted to increase the temperature of feed water through a heat exchanger. In this study, a shell and tube heat exchanger was chosen to increase the feed water temperature with the flow rate of 0.55 kg/s to reach the target of 80 °C. Meanwhile, the mass flow rate of the exhaust gas is 0.9 kg/s with a temperature estimated at 300 - 310 °C. The basic design of the heat exchanger is created to get the main dimensions such as the cross-sectional area (A), the length of the tube (L), the outer diameter of the tube (do) and the total of tube (N). Finally, the main dimensions are optimized by the Taguchi experimental method to obtain the most optimal design.
