In incinerators, the flue gas produced after waste is burned contains a large amount of harmful substances and incompletely burned organic compounds, such as carbon dioxide, carbon monoxide, nitrogen oxides, volatile organic compounds, etc.

These flue gases first pass through the primary combustion chamber and then enter the secondary combustion chamber. In the secondary combustion chamber, through the oxygen supply system and appropriate temperature conditions, incompletely burned organic matter and harmful gases can be recombusted at high temperatures and further decomposed into harmless substances such as water and carbon dioxide.

The secondary combustion chamber is usually designed to be at high temperature to ensure complete combustion of organic matter. The temperature control system can maintain the temperature in the secondary combustion chamber within an appropriate range to ensure the progress of the combustion reaction.

After treatment in the secondary combustion chamber, the harmful substances in the emitted flue gas are greatly reduced, reaching environmental protection emission standards. The waste gas treated in this way can be discharged into the atmosphere through the chimney, greatly reducing the impact on the environment and human health.
