Slugging in a fluidised bed can be avoided by using_____________________?
Correct answer: C. Shallow beds of solids and proper choice of particle size
- A. Tall narrow vessel
- B. Deep bed of solids
- C. Shallow beds of solids and proper choice of particle size
- D. Very large particles
Explanation
Slugging is reduced by using a shallow bed and selecting particles that fluidise uniformly, which limits the growth of large gas pockets. Tall narrow vessels, deep beds, and very large particles promote unstable bubbling or slug formation.
