The placement of deresonating baffles in a Shell and Tube heat exchanger is critical for minimizing resonation and optimizing flow. Baffles should be positioned parallel to the tube bundle, particularly in areas identified as prone to resonation, which can be detected using a stethoscope. Anti-swirl baffles are typically installed near the tube inlets and outlets. Additionally, understanding the thermal properties of white liquor, a mixture of NaOH, Na2S, and Na2CO3, is essential for effective design and operation.

Anyone knows how to place the DERESONATING BAFFLES in a Shell and Tube heat Exchanger? How does it look likes?
croghan27 said:I am sure some engineer can locate the areas that are most prone to resonating, or even just someone with a stethescope - that is the place for the interiour baffles ... the ones I am familiar with lie within and to parallel the tube bundle.
I have also seen anti-swurrl (is that a word?) baffles placed near the tube inlet and outlets. If they are within the bundle they have to be removed for maintenence on the tube sheets etc - if inside the piping leading to the exchanger, not.
Other than that - differences in flow and pressure on the shellside can make a big difference.
