Problems solved by technology

[0002] Sintered corundum is produced in a vertical kiln, and the burners are generally water-cooled burners. This kind of burner is used for a long time. Due to the erosion of the inner wall of the burner by the minerals in the tap water, it is easy to cause water leakage and blockage of the burner with precipitated scale. channel, causing the gun body to burn and melt, and the water to flow into the kiln to affect the sintering of the product
At the same time, the replacement of the burner when it fails is very inconvenient for workers due to its heavy weight.

Abstract

The invention relates to a burner, which comprises an inner gas duct and an air duct arranged outside the gas duct. An igniter is arranged in the gas duct. The burner can be operated for a long time at the high temperature, and is few in maintenance times, high in burning efficiency and large in jet kinetic energy.

Description

technical field [0001] The invention designs a burner used in an industrial kiln, in particular relates to a burner for producing plate-shaped corundum with a shaft kiln. Background technique [0002] Sintered corundum is produced in a vertical kiln, and the burners are generally water-cooled burners. This kind of burner is used for a long time. Due to the erosion of the inner wall of the burner by the minerals in the tap water, it is easy to cause water leakage and blockage of the burner with precipitated scale. The channel causes the gun body to burn and melt, and the water flows into the kiln to affect the sintering of the product. At the same time, the replacement of the burner when it breaks down is very inconvenient for workers because of its heavy weight. Contents of the invention [0003] The purpose of the present invention is to provide a burner that can cool the burner well without corroding the burner. [0004] For this reason the technical scheme of the pres...
