Flue gas waste heat recovery usually uses two methods: one is to preheat the workpiece; the other is to preheat the air for combustion.
Flue gas preheating of the workpiece requires a large volume for heat exchange and is often limited by the operating site.
Preheated air combustion is a better method, generally configured in the heating furnace, but also to strengthen the combustion, accelerate the furnace heating rate, improve the thermal performance of the furnace. This can meet the requirements of the process, but also to obtain a significant comprehensive energy-saving effect.
