Post Combustion Chambers Used For waste incineration plants

Secondary combustion chamber

A secondary combustion chamber, also known as a post-combustion chamber or afterburner, is a component commonly used in certain types of combustion systems. Its purpose is to further burn any unburned or partially burned fuel and combustible gases that remain in the exhaust gases from the primary combustion chamber.

The primary combustion chamber is where the initial combustion process takes place, typically in an engine or a furnace. However, in some applications, the combustion process may not be complete, resulting in the release of pollutants or unburned fuel into the exhaust stream. This is where the secondary combustion chamber comes into play.

The secondary combustion chamber provides a controlled environment where additional oxygen is introduced to facilitate the complete combustion of any remaining fuel and other combustible compounds. This is usually achieved by injecting additional air or other oxidizers into the exhaust gases. The increased oxygen concentration promotes a secondary combustion process, allowing for more complete combustion of the remaining fuel.

The flue gas generated after the regeneration of powdered carbon and granular carbon enters the secondary combustion chamber, and the

combustion chamber temperature is heated to above 1100°C through the burner in the secondary combustion chamber. Suitable high calorific value

liquid waste can be injected into the secondary combustion chamber instead of fuel, and the flue gas is The residence time of the secondary

combustion chamber exceeds 2 seconds, allowing the trace organic matter and dioxins in the flue gas to be fully decomposed and completely

burned, ensuring that the hazardous waste entering the exhaust system is fully burned
