Use of pulverised coal in boilers provides____________________?
Correct answer: C. Better combustion
- A. Higher calorific value
- B. Smokeless burning
- C. Better combustion
- D. Less erosion on furnace wall
Explanation
Pulverising coal greatly increases its surface area, allowing rapid and more complete mixing with air and therefore better combustion. It does not increase the coal’s inherent calorific value.
