ABSTRACT:
Process and apparatus for the changing the temperature of a gaseous stream using flexible fluoropolymer tubes having specified dimensions and configurations. The tubes are separated by spaces which serve the dual purpose of regulating the free span of each tube segment between spacers at a distance of about 20 to 90 cm and separating successive rows of tubes by about 1.25 to 3.0 times the diameter of the tubes. This configuration permits a low frequency, high amplitude vibration of the tubes that has the dual effect of a self-cleaning function and an increase in the heat transfer coefficient of the tubes.
