Coal is pulverised before burning in large capacity boiler furnaces mainly to____________________
Correct answer: A. Ensure its complete combustion
- A. Ensure its complete combustion
- B. Facilitate easy ash removal
- C. Enhance its calorific value
- D. Provide trouble free operation
Explanation
Pulverising coal increases its surface area, allowing better contact with air and making combustion more nearly complete. It does not increase the coal's inherent calorific value or primarily assist ash removal.
