Fuel economy in an industrial furnace operation cannot be achieved by the use of__________________?
Correct answer: A. Stoichiometric combustion air
- A. Stoichiometric combustion air
- B. Non-preheated combustion air
- C. Combustion air not enriched with oxygen
- D. Recuperators
Explanation
Exact stoichiometric air gives no allowance for mixing limitations, so complete combustion cannot reliably be achieved throughout an industrial furnace. A small controlled excess of air is normally needed, making stoichiometric air the unsuitable choice.
