Catalytic Combustion Equipment

Lvquan high quality Catalytic combustion is a purification method that uses a catalyst 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 catalyst accelerating the process of oxidation and decomposition, most hydrocarbons can be completely oxidized through the catalyst at temperatures ranging from 300 to 450 ℃.

Introduction to catalytic combustion equipment or devices: A catalytic combustion device refers to a device or device that burns under the action of a catalyst. The working principle of a catalytic combustion device is to use a catalyst to perform flameless combustion of organic waste gas at a lower ignition temperature, causing the organic waste gas to decompose into non-toxic carbon dioxide and water vapor. The catalytic burner electrical control system consists of PLC controller, text display, variable frequency speed controller, igniter, ultraviolet sensor, thermocouple and other electrical control equipment, as well as fan. In addition, the proportion of gas and air is adjusted by zero pressure valve. The entry also provides examples of HC type series organic gas catalytic combustion devices and LF-VC type direct catalytic decomposition oxidation devices, as well as unsafe factors and management measures in the use of catalytic combustion devices.

Catalytic combustion process

The method of using catalysts to reduce combustion temperature and accelerate the complete oxidation of toxic and harmful gases during chemical reactions is called catalytic combustion. Due to the fact that the carrier of the catalyst is made of porous materials with a large specific surface area and suitable pore size, when organic gases heated to 300-450 ℃ pass through the catalytic layer, oxygen and organic gases are adsorbed on the catalyst surface of the porous material, increasing the chances of contact and collision between oxygen and organic gases, improving activity, and causing violent chemical reactions between organic gases and oxygen to generate CO2 and H2O, while generating heat, thereby making organic gases non-toxic and harmless gases.

The catalytic combustion device mainly consists of a heat exchanger, combustion chamber, catalytic reactor, heat recovery system, and exhaust chimney for purifying flue gas, as shown in the right figure. The purification principle is that before entering the combustion chamber, the raw gas is preheated by a heat exchanger and sent to the combustion chamber. It reaches the required reaction temperature in the combustion chamber, and the oxidation reaction is carried out in the catalytic reactor. After purification, the flue gas releases some heat through the heat exchanger and is then discharged into the atmosphere through the chimney.
