Working principle:
Similar to the principle of CO, under the action of a catalyst, organic matter is oxidized and decomposed into carbon dioxide and water at relatively low temperatures (280-320 ℃) through the active components of the catalyst, forming flameless combustion.
Usually, complete oxidation of VOCs (direct combustion or thermal combustion) requires higher temperatures and longer residence times. Taking benzene as an example, without a catalyst, to achieve complete oxidation, the temperature needs to be above 800 ℃ and the residence time should be at least 1-2 seconds. With the participation of catalysts, the complete oxidation temperature and residence time significantly decrease, requiring only 250-400 ℃ and 0.1-0.2s, fully demonstrating the superiority of catalytic combustion method.

Technical advantages:
1. Lowest operating costs, no need to consume a large amount of electricity or gas, saving operating costs;
2. Not producing secondary pollutants such as nitrogen oxides (NOx);
3. Fully automatic control, resistant to impact loads, not easily affected by changes in pollutant concentration and temperature.
4. Efficient heat recovery rate, RCO heat recovery efficiency ≥ 95%;
5. High safety and purification efficiency of over 98%.
Scope of application:
1. Suitable for industries such as electronics, painting, petrochemicals, printing, machinery, electronics, metallurgy, steelmaking, and building materials.
2. Widely applicable, especially suitable for treating high volume and low to medium concentration exhaust gases. For multi-component and non recyclable exhaust gases, catalytic oxidation method has better treatment effect.
