Coals used for the generation of producer gas should have ____________________?
Correct answer: B. High volatile matter content
- A. High caking index
- B. High volatile matter content
- C. Low fusion point of ash
- D. Very low ash content (8-10%)
Explanation
Coal for producer gas should ignite readily, and higher volatile matter promotes ignition and gas formation. High-caking coal and low-ash-fusion coal are undesirable because they can cause clinkering and operating difficulties.
