Safety factor of the heat exchanger and shell-side heat transfer coefficient
Thread Content
What is the safety factor for heat exchangers? What value is generally used in the design of shell-and-tube heat exchangers? Additionally, I would like to ask how the heat transfer coefficient of the shell side of a tubular heat exchanger should be selected during design? Thank you very much.
I think this safety factor is a margin for the heat exchange area, usually around 1.15–1.2. As for the heat transfer coefficient on the shell side, it depends on the physical properties of the specific material and the structure of the shell side.
The safety factor should be related to the strength of pressure vessels, but I’m not exactly sure. In the design calculations for heat exchangers, the heat transfer coefficient is generally taken as 0.95 to 0.98
