ombustion of pulverised coal compared to the lumpy coal __________________?
Correct answer: B. All A., B. & C.
- A. CA. Provides better control of furnace temperature
- B. All A., B. & C.
- C. Provides higher thermal efficiency & flame temperature
- D. Facilitates combustion with lower excess air
Explanation
Pulverising coal increases its surface area and gives more uniform mixing with air, allowing better temperature control and combustion with less excess air. The resulting combustion generally gives higher thermal efficiency and flame temperature, so all listed effects apply.
