Oxygen-enriched combustion technology is an energy efficient combustion technology, which can intensify the flame stability, increase the temperature and reduce fuel consumption. Aiming at forge furnace as research object, the effects of oxygen-enriched concentration in combustion air on thermal parameters is studied. The mainly thermal parameter included the fuel combustion procedure, thermal transfer, heating time and the amount of fuel combustion. The results show that with the oxygen concentration increasing, the gas emission coefficient and radiation coefficient is higher. While the heating time, the volume of combustion air requirement, flue gas production and fuel consumption is decreased. Additionally, the study suggests that forge furnace can obtain maximize economic benefit when oxygen concentration is about 30%.
