AI Technical Summary

Technical Problem

When the existing burners that combine atmospheric and infrared are ignited and adjusted the flame size, the fire transfer efficiency between the inner and outer fire covers is poor, resulting in ignition instability and difficulty in flame regulation.

Method used

An ignition groove is set at one end of the fire transmission channel near the inner fire cover. The notch of the ignition groove is facing the inner fire cover, and an ignition groove hole is set on the bottom of the ignition groove to allow flame or gas in the fire transmission channel to spray to the inner fire cover through the ignition groove.

Benefits of technology

The ignition efficiency of the inner fire cover and the fire transmission efficiency between the inner and outer fire covers are improved, and the stability of the ignition and the flexibility of flame adjustment are enhanced.

Abstract

The combustor comprises an inner fire cover and an annular outer fire cover arranged on the periphery of the inner fire cover, a fire transferring channel extending in the radial direction is formed in the outer fire cover, one end of the fire transferring channel corresponds to the inner fire cover, and the other end of the fire transferring channel penetrates through the outer fire cover and corresponds to the periphery of the outer fire cover; a U-shaped ignition groove is formed in the end, close to the inner fire cover, of the fire transferring channel and extends from the inner wall of the fire transferring channel to the outer wall of the fire transferring channel, a groove opening of the ignition groove faces the inner fire cover, and an ignition groove hole communicated with the interior of the outer fire cover is formed in the groove bottom of the ignition groove. The ignition groove is formed in the end, close to the inner fire cover, of the fire transferring channel, the groove opening of the ignition groove faces the inner fire cover, the ignition groove hole is formed in the groove bottom of the ignition groove, flames or fuel gas in the fire transferring channel can be sprayed to the inner fire cover through the ignition groove, and the ignition efficiency of the inner fire cover is improved; and the fire transfer efficiency between the inner fire cover and the outer fire cover is improved.
