In the production process of petroleum and petrochemical industry, offshore petroleum and steel smelting enterprises, a large amount of unrecoverable combustible gas exists, and the combustible gas is discharged into the atmosphere, so that the production safety is greatly damaged, the environment is seriously polluted, and in order to prevent the combustible gas from being discharged into the atmosphere, the production safety is greatly damaged, the environment is seriously polluted, and a flare system is required to perform reliable combustion treatment. In the prior art, a secondary ignition mode is adopted by a torch system to ensure the reliable combustion of the discharged gas of the torch. The secondary ignition is that 3-4 pilot lamps with open flame for a long time are arranged around the main torch, when the combustible gas to be treated is discharged, the combustible gas contacts the open flame of the pilot lamps to burn immediately, and the combustible gas which is discharged and cannot be recovered is formed by flame burning. The traditional pilot burner adopted in the prior art is used for igniting the combustible gas by the ignition control equipment and keeping a long-burning state, and works continuously 24 hours a day, and normal production is 365 days a year. The problems are:
