Low temperature oxidation of coal is accelerated by the____________________?
Correct answer: A. Storage in large heaps
- A. Storage in large heaps
- B. Storage in compressed piles
- C. Absence of porous or friable particles
- D. All A., B. and C.
Explanation
Large coal heaps retain the heat generated by slow oxidation, causing the temperature and oxidation rate to rise further. This is why bulk storage promotes low-temperature oxidation and possible spontaneous heating.
