What is the core working principle of catalytic combustion?

The core focus is on reducing the activation energy of reactions.

• Without a catalyst: High temperatures, such as 700-800°C, are required to combust and decompose VOCs, i.e., direct combustion.
• With a catalyst: The catalyst surface can adsorb oxygen and VOCs molecules, making them more reactive and significantly lowering the reaction temperature to below its ignition point. This process is flameless combustion, offering high safety.

What are the main components of the catalytic combustion system?

A typical system includes:

• Pre-treatment Unit: Filters out dust and particulate matter from exhaust gases to prevent catalysts from becoming poisoned and failing.
• Heat Exchanger: A Core Energy-Saving Component. Utilizes the heat from the high-temperature, clean gas after reaction to preheat the low-temperature exhaust gas entering the system, significantly reducing the energy consumption of the system.
• Preheat Chamber (Heating Chamber): Heats waste gases to the ignition temperature required for catalytic reactions using electrical or gas heating.
• Catalytic Reactor (Catalytic Bed): Core reaction zone, filled with catalyst internally.
• Fan: Provides the power for waste gases to flow within the system.
