In burners for various combustion furnaces, it is often necessary to take the burners out of the combustion furnace for purposes such as maintenance, inspection, and cleaning of the burners. For this reason, when it comes to burners, priority is given to ease of taking out the burner, and as a result, the sealing of the take-out portion of the burner has sometimes been neglected. Particularly in forced draft combustion furnaces, if the seal is insufficient, high temperature flammable gas may leak out of the furnace during operation, creating a dangerous situation, which is a serious problem from a safety standpoint. was causing

があつた。 Conventionally, the method of sealing the outlet of the burner was to continuously pump sealing air into the sealing section, but this method did not provide a perfect sealing effect because the sealing was performed using air pressure.
Additionally, a string-like asbestos packing is wrapped around the sealing part to seal it. However, as the string-like asbestos packing has poor compressibility and resilience, it must be tightened strongly to form a complete seal, which increases the sliding resistance when removing the burner. There was a problem that the parts were easily damaged due to wear.
