Flue Gas Air Heater

A flue gas air heater is a device used to transfer thermal energy from flue gas to air in order to heat the air. This type of heater is often used in industrial processes to recover thermal energy from exhaust gases in order to save energy and improve process efficiency.

Flue gas air heaters typically work by flowing the flue gas and air through a separate heat exchange surface, allowing the heat in the flue gas to be transferred to the air, thereby heating the air. This heat exchange usually takes place in a closed unit, ensuring efficient heat transfer between the flue gas and the air.

This type of heater is usually applied in the following situations:

Industrial Exhaust Gas Recovery: In industrial processes, the flue gases produced usually contain a large amount of heat energy, and flue gas air heaters can be used to recover the heat energy from these exhaust gases and use it to heat the air or other fluids required in the process.

Energy saving: By recovering thermal energy from exhaust gases, energy consumption in industrial processes can be reduced, reducing carbon emissions and energy costs.

Temperature regulation: In some industrial processes, air needs to be heated to achieve specific temperature requirements, and flue gas air heaters can provide this heating function.

Flue gas treatment: In some cases, flue gas can be treated by exchanging it with air, for example to reduce the humidity in the flue gas or to remove certain hazardous substances.
