AI Technical Summary

Technical Problem

When the furnace is working, grease and impurities in the exhaust gas will enter the combustion chamber and shell, causing corrosion of the equipment and damaging the service life of the equipment. At the same time, the heat of the exhaust gas cannot be effectively recycled, resulting in low energy utilization efficiency.

Method used

A fire furnace with waste heat recovery device is designed. The exhaust gas discharged through the air outlet pipe is heated by heating the water tank. The water vapor is sent into the air outlet hole at the bottom of the air outlet hood through the air supply pump, and the waste gas is humidified and absorbed into the oil and impurities in the waste gas. Reduce direct discharge pollution to the environment and the human body, and use a combustion-assisted fan to ignite water vapor to improve combustion efficiency.

Benefits of technology

It effectively reduces the corrosion of oil and impurities in the waste gas on the equipment, improves the safety of equipment use, and improves the efficiency of energy utilization through waste heat recovery, and reduces pollution to the environment and the human body.
