Advantages of fluidised bed combustion are ____________________?
Correct answer: D. All A., B. & C.
- A. Reduced NOx formation in flue gas
- B. Lower furnace operating temperature
- C. High heat transfer rate
- D. All A., B. & C.
Explanation
Fluidised-bed combustion operates at a lower, more uniform temperature, which suppresses thermal NOx formation, while intimate gas-solid contact gives a high heat-transfer rate. Therefore all three listed advantages apply.
