Low temperature oxidation and spontaneous combustion of freshly mined coal is accentuated, if __________________?
Correct answer: D. All A., B. and C.
- A. It contains large amount of volatile matter
- B. It is stored in tall heaps
- C. Smaller fines are stored in large quantity
- D. All A., B. and C.
Explanation
Volatile coal oxidizes readily, while tall heaps retain heat and fine particles provide a large surface area for oxidation. These three conditions therefore promote low-temperature oxidation and spontaneous combustion.
