VOCs exhaust gas burner data Xiamen catalytic combustion

Description :

　　Catalytic combustion is a purification method that uses catalysts to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the acceleration of the oxidation decomposition process by the catalyst, most hydrocarbons can be completely oxidized by the catalyst at temperatures of 300-450 ℃.

　　Compared with the thermal combustion method, catalytic combustion requires less auxiliary fuel, consumes less energy, and has smaller equipment and facilities. However, the promotion and application of this method in industrial production processes have been affected by issues such as catalyst poisoning, replacement of catalytic beds, and high cleaning costs.

　　Catalytic combustion treatment is widely used in the purification of harmful organic waste gases emitted from workshops in industries such as petroleum, chemical, rubber, coating, and printing. Organic waste gases such as benzene, alcohols, and ethers can all be purified. The device has a complete system design, complete supporting equipment, high purification efficiency, and high degree of automation. It can effectively purify the workshop environment, eliminate pollution, improve working conditions, ensure the health of workers, and solve secondary pollution. Suitable for organic waste gases with low concentrations (50~1000ppm) and low economic value for recovery, and not suitable for adsorption recovery treatment, especially for high air volume treatment scenarios. The characteristics of processing high air volume and low concentration exhaust gas include secondary waste heat recovery when the concentration is slightly higher, greatly reducing production and operation costs.

　　The main features of RCO type exhaust gas treatment catalytic combustion equipment and high-temperature air combustion technology are:

　　1. Adopting a high-temperature air flue gas waste heat recovery device, alternately switching between air and flue gas to flow through a thermal storage body, can largely recover the sensible heat of high-temperature flue gas, thus achieving waste heat recovery;

　　2. Preheat the combustion air to a temperature level of over 1000 ℃ to form a new type of flame that is distinct from traditional flames such as diffusion flames and premixed flames, creating an excellent uniform temperature distribution inside the furnace;

　　3. By organizing combustion in a lean oxygen state, the significant generation of high-temperature thermal nitrogen oxides (NOx) under normal conditions is avoided. Therefore, this technology has generated significant economic and social benefits in practical applications.
