Pick out the wrong statement pertaining to shell and tube heat exchanger_______________?
Correct answer: F. Bracket supports are used for horizontal shell, while saddle support is used for vertical shell
- A. Clearance between shell & baffles and between tube & baffles should be minimum to avoid
- B. by-passing of the fluid, but it should be enough to permit the removal of tube bundle
- C. Baffles are supported independently of the tubes by tie rods and positioned by spacers
- D. Tie rods are fixed at one end in the tube sheet by making blind holes and the minimum
- E. number of tie rods is 4 with at least 10 mm diameter
- F. Bracket supports are used for horizontal shell, while saddle support is used for vertical shell
Explanation
Horizontal shell-and-tube exchangers are normally supported on saddle supports, while vertical units use brackets, lugs, or skirt-type supports. Statement f reverses these arrangements and is therefore the wrong statement.
