Fusion point of coal ash generally varies from 1000 to 1700° C. Ash having fusion point less than _______________ °C is liable to form clinker?
Correct answer: A. 1100
- A. 1100
- B. 1250
- C. 1350
- D. 1400
Explanation
Coal ash with a fusion temperature below about 1100°C softens and fuses readily on furnace grates, producing clinker. Higher-fusion-point ash is less prone to this troublesome slagging.
