Calorific value of a typical dry anthracite coal may be around _____________ Kcal/kg?
Correct answer: C. 8000
- A. 1000
- B. 4000
- C. 8000
- D. 15000
Explanation
Dry anthracite is a high-rank coal with a calorific value commonly near 8,000 kcal/kg. Values of 1,000 or 4,000 kcal/kg are too low for anthracite, while 15,000 kcal/kg is unrealistically high for coal.
