[0002] The waste gas combustion furnace is a device that uses the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible harmful gases to the reaction temperature, thereby causing oxidation and decomposition. The direct-fired waste gas combustion furnace is a type of combustion furnace. The so-called "direct-fired" means that only the waste gas is burned and the heat is not recovered. It is suitable for waste gas treatment of spraying and drying equipment, and purification of harmful gases emitted by petrochemical, pharmaceutical and other industries.

[0003] Based on the above, the inventors found that: the existing waste gas combustion furnace controls the feed of waste gas through a control valve. Since the organic waste gas of the waste gas combustion furnace contains particulate impurities, the feed control valve is prone to accumulate particulate impurities inside during long-term control work, affecting the service life of the control valve, and the feed control valve is generally large in size, inconvenient to disassemble and install, resulting in difficulty in maintenance. Therefore, in view of this, the existing structure is studied and improved, and a feed structure for a direct-fired waste gas combustion furnace is provided, in order to achieve a more practical purpose.
