Using Turbulators to increase heat transfer capabilities
Using Turbulators to increase heat transfer capabilities
(OP)
How much of an increase can you expect (ballpark) from inserting turbulators into an existing shell and tube heat exchanger? Existing heater is 10.92 MMBtu/hr. Tube side is feedwater shell side is natural gas.

Thermal resistances are calculated in the exact same manner that electrical resistances are calculated. The gas-side resistance here might be a couple of orders of magnitude larger that the water-side resistance.

Therefore, there will be no improvement in the overall film coeficient.
Turbulators are used mainly when having viscous fluids inside the tubes.
