The working principle of catalytic combustion equipment is roughly divided into three processes: adsorption gas, desorption gas, and catalytic combustion process. The essence of the gas-solid phase catalytic reaction in the catalytic purification device is the oxidation effect of active oxygen.

Matters needing attention in the production of catalytic combustion environmental protection equipment manufacturers.

1. Auxiliary fuel and combustion-supporting. Catalytic combustion generally uses natural gas as auxiliary fuel, but also can use fuel oil, electric heating, etc. as auxiliary fuel. Combustion generally uses purified gas. If the purified gas cannot be used as combustion support, air should be introduced to support combustion.

2. Higher conversion speed. Since catalytic combustion is an irreversible exothermic reaction, no matter what stage the reaction progresses, it should be carried out at the highest possible temperature to obtain a higher conversion rate. However, the operating temperature is often limited by certain conditions, such as the heat-resistant temperature of the catalyst, the availability of high-temperature materials, the supply of heat energy, and whether it is accompanied by side reactions. Therefore, the actual production should be appropriately selected according to the actual situation.

3. Air flow and temperature are evenly distributed. To make the air flow and temperature distribution uniform across the surface of the catalyst, and to ensure that the flame does not directly contact the surface of the catalyst, the combustion chamber must have sufficient length and space. The catalytic combustion device should have a good thermal insulation effect. The furnace body is generally lined with refractory material in the outer shell of steel structure, or with double-layer sandwich wall structure.

4. Easy to clean and replace. The catalyst reactor should generally be designed with a mold structure that is convenient for loading and unloading to facilitate cleaning and replacement of the catalyst carrier.
