Discussion on the baffle spacing issue in evaporators
Thread Content
Dear sea friends, how exactly should the spacing between baffle plates be determined when designing an evaporator? For example, if the diameter of the evaporator is 1450 mm and the length of the heat exchange tubes is 6 m,
A shy question: what is a baffle?
Changing the flow direction of the shell-side fluid to increase the residence time and thereby improve heat transfer efficiency can be found in the relevant manuals
Hmm, it seems our company doesn’t have this
As long as you have a heat exchanger, it’s there inside.
There is no fixed value for the spacing; it can range from 20% to 100% of the diameter. However, one thing mentioned above is incorrect – some evaporators do not have baffle plates, especially those of the kettle type
I’m sorry; I was on a business trip recently and didn’t have time to reply. For the shell side where the fluid is steam, the spacing of the baffles seems to have little impact. But for the shell side where the fluid is a liquid, can it also be set at 20%–100% of the diameter?
Sure, just choose a suitable value; there are no strict requirements.
I was wondering if the senior could provide some information on baffle design; I would be extremely grateful
