Working principles and efficiencies of different types of graphite heat exchangers and falling film absorbers
Thread Content
We are now selecting a graphite heat exchanger. We can calculate the heat exchange area, but how should we decide whether to use a tubular type or a plug-and-plate type, and whether to go with circular or square tubes? How do we make this choice? Regarding falling film absorbers, is a tubular type better or a plug-and-perforated type? Which one works better? Please help discuss this.
We use shell-and-tube type, and it works well.
If the heat exchange area is large, it is recommended to use block-and-hole type exchangers; these are similar to U-tube exchangers. If the area is small, circular tube arrays are a better choice.
I’ve seen shell-and-tube types, and they work well
