Discussion
Match each device in List I with its principal limitation in List II.
List I
A. Gravity settling chamber
B. Fabric filter
C. Electrostatic precipitator
D. Wet scrubber
List II
1. Sensitive to dust resistivity
2. Useless on fine particulate
3. Produces a slurry effluent
4. Damaged by heat and by condensation
Select the correct match.
Answer: C
Correct answer: A-2, B-4, C-1, D-3
Each device has one characteristic weakness. A settling chamber is useless on fine particulate, since Stokes velocity falls with the square of diameter. A fabric filter is damaged by heat above the fabric limit and blinded by condensation. A precipitator depends on the dust resistivity lying within a workable window. A wet scrubber transfers the problem to a slurry that must be treated.
