Question

I need A background about triple heat exchanger

Answer 1

Answer:

The triple concentric tube heat exchanger is a modified constructive version of double concentric tube heat exchanger by adding an intermediate tube. This intermediate tube improves the heat transfer by increasing the heat area per unit length.

The triple concentric heat exchangers have some advantages compared to tube in tube heat exchangers, as larger surface area for heat transfer per unit length and higher overall heat transfer coefficients.

Adding the third tube the thermal contact between the fluids was improved. Also, by using these types
of heat exchangers can be obtained technical and economic advantages due to the possibility of heat
exchange between three fluids in one equipment. The heat exchangers with three concentric tubes are
used specially in heating processes food industry, cooling processes, pasteurization/sterilization,
congelation and concentration.
