Explanation
Fuel economy in industrial furnaces is typically enhanced by using preheated or oxygen-enriched air and by recovering heat through devices like recuperators. However, using exactly stoichiometric combustion air—where air supply matches the exact amount needed for complete combustion—does not improve fuel efficiency, as it does not account for heat losses or incomplete combustion.
