On the design temperature of heat exchanger tube sheets
Thread Content
In examples related to heat exchangers, the design temperature of the tube sheet is often mentioned. The question is: how is this temperature determined? An example will be provided to illustrate this. I have a question. Thank you
Are you a student? Let me answer your question. Regarding the temperature design issue, it is determined based on different operating conditions. For example, in the food industry, in a scenario where hot water needs to be generated, if your process design requires hot water at 95 degrees, you can design a heating process that raises cold water from 25 degrees to 95 degrees. The heat source is steam at 120 degrees, and a plate heat exchanger is used for heat exchange. In this case, the temperature of the steam on the hot side is set at 120 degrees – 90 degrees, while the temperature of the hot water on the cold side is set at 25 degrees – 95 degrees. The flow rate will be designed separately according to the process requirements; I hope my answer is helpful to you. The design parameters are all determined based on different manufacturing processes.
