Description

Technical Field

[0001] This utility model belongs to the technical field of high-frequency induction ignition torch head, specifically relating to a high-frequency induction ignition torch head. Background Technology

[0002] A high-frequency induction ignition torch is an industrial-grade ignition device that uses high-frequency electromagnetic induction to generate high temperatures to ignite natural gas, fuel oil, or other combustible media. It is commonly found in industrial combustion equipment requiring stable and efficient ignition, such as boilers, furnaces, and incinerators.

[0003] The high-frequency induction ignition torch head is mainly used for hydrocarbon gases, industrial waste gases, biomass gases, and special process gases.

[0004] However, since high-frequency induction ignition torch heads are often installed inside boilers, and the electrodes inside the high-frequency induction ignition torch heads need to be replaced regularly, the high-frequency induction ignition torch heads are directly installed inside the boilers, requiring manual entry into the boilers to remove the high-frequency induction ignition torch heads and replace the electrodes. This makes it impossible to quickly replace the electrodes inside the high-frequency induction ignition torch heads inside the boilers. Utility Model Content
