1. What is Baffle Spacing in Heat Exchangers?

Definition: Baffle spacing refers to the distance between adjacent baffles within the shell side of a shell-and-tube heat exchanger.

Purpose: Baffles create turbulence in the shell-side fluid, improving heat transfer efficiency and supporting tubes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L_{Baffle} \) — Baffle spacing (meters)
• \( L_{Tube} \) — Length of the tube (meters)
• \( N_{Baffles} \) — Number of baffles

Explanation: The tube length is divided by the number of gaps between baffles (which is always one more than the number of baffles).

3. Importance of Proper Baffle Spacing

Details: Correct baffle spacing ensures optimal heat transfer, prevents tube vibration, and maintains proper fluid velocity.

4. Using the Calculator

Tips: Enter the total tube length and the number of baffles. The calculator will determine the equal spacing between all baffles.

5. Frequently Asked Questions (FAQ)

Q1: Why is the number of gaps one more than baffles?
A: There's a gap before the first baffle and after the last baffle, plus spaces between them.

Q2: What's a typical baffle spacing range?
A: Typically between 20-50% of the shell diameter, but depends on application.

Q3: Can baffle spacing be unequal?
A: Yes, but this calculator assumes equal spacing for simplicity.

Q4: How does baffle spacing affect performance?
A: Closer spacing increases turbulence and heat transfer but also increases pressure drop.

Q5: What if I need to calculate number of baffles?
A: Use our reverse calculator that determines number of baffles given desired spacing.
