Combustion of fuel in a furnace with oxygen enriched air results in higher__________________?
Correct answer: B. Flame temperature
- A. Flue gas volume
- B. Flame temperature
- C. Fuel consumption
- D. Stack loss
Explanation
Oxygen enrichment reduces the nitrogen carried into the furnace, allowing more of the released heat to raise the combustion-gas temperature. It also reduces flue-gas volume and can lower fuel consumption, so flame temperature is the intended result.
