With increase in C/H ratio of a fuel, the dew point of flue gases______________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remain same
- D. May increase or decrease; depends on the type of fuel
Explanation
A higher C/H ratio means less hydrogen is burned per unit of fuel, so less water vapour is produced. Lower water-vapour partial pressure lowers the flue-gas dew point.
