Do heat exchangers with water vapor flowing in the shell side really need baffle plates?
Thread Content
From the perspective of condensation principles, it seems unnecessary; from the standpoint of the maximum unsupported span, it seems necessary again. In terms of thermal stress, it seems unnecessary, but considering self-weight and vibration prevention, it seems necessary as well. It’s a bit confusing… I hope experts can come in and discuss this
This needs to be considered comprehensively; the use of baffle plates helps improve the heat exchange efficiency... Additionally, since steam is used in the shell side, it doesn’t seem appropriate to classify it as a condenser...
Yes, at least it can increase the heat exchange value
I didn’t say it was a condenser; I was talking about the principle of heat release due to the condensation of water vapor
The heat release coefficient of water vapor is independent of velocity, so there’s no need for that
From a heat transfer perspective, it is not necessary； From the perspectives of strength, support, and shock absorption, other support methods can be used instead of baffle plates ； Conclusion: Baffles can be omitted.
The baffle may not be necessary; if the calculations fail due to an excessively large unsupported span, support plates can be added.
