Softening temperature of coal ash is a measure of the _____________ of coal?
Correct answer: A. Clinkering tendency
- A. Clinkering tendency
- B. Coking tendency
- C. Caking tendency
- D. Size stability
Explanation
Ash softening temperature indicates when ash particles begin to deform and stick, which determines their tendency to form fused clinker on a grate. It therefore measures clinkering tendency rather than coal caking or coking tendency.
