Description

Large-discharge side-firing ground sealing torch Technical Field The utility model relates to the technical field of combustion, in particular to a large-displacement side-firing ground sealing torch. Background In the industrial production process, a large amount of combustible waste gas can be generated in many occasions, such as industries of petrochemical industry, coal chemical industry, natural gas exploitation and the like, if the waste gas is directly discharged into the atmosphere, serious environmental pollution can be caused, and the large-discharge-capacity side-burning ground sealing torch is used as special equipment for treating the combustible waste gas, so that the waste gas can be efficiently burnt in a sealed space and converted into harmless substances such as carbon dioxide, water and the like, thereby achieving the dual purposes of environmental protection and safety. In actual operation, the gas discharge capacity of the large-discharge-capacity torch is not constant all the time, but can fluctuate within a certain range, for example, in chemical production, the discharged gas quantity can be changed in different production stages or on-off of equipment, when the gas discharge capacity is smaller, if the area of an air inlet is too large, the quantity of air entering the large-discharge-capacity torch is too large, the temperature in a combustion chamber is reduced, the combustion efficiency is influenced, and even flameout phenomenon can occur, and if the area of the air inlet is too small, the air supply is insufficient, the fuel gas cannot be fully combusted, the combustion efficiency is reduced, so that the large-discharge-capacity side-firing ground-sealing torch is proposed.
