Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner structure of an annealing furnace. Background Art

[0002] Heat treatment furnaces are divided into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are mainly used for annealing of large carbon steel and alloy steel parts; tempering of surface quenched parts; stress relief annealing of welded parts, aging and other heat treatment processes. The heating methods include electric heating, oil, gas, coal, and hot air circulation. Annealing furnace is a new type of heat exchange equipment. Annealing furnace is an energy-saving periodic operation furnace with super energy-saving structure. It adopts fiber structure and saves 60% of electricity. The burner structure of annealing furnace is an indispensable part of annealing furnace operation.

[0003] In the process of use, the burner structure of an existing annealing furnace is designed through the first air inlet pipe, the second air inlet pipe and the igniter, so that the combustion gas enters through the first air inlet pipe and the second air inlet pipe when the device is in use, and then ignites it through the igniter, thereby heating the metal in the annealing furnace. However, when the burner structure of the existing annealing furnace is placed for a long time, the valve inside the device is easy to loosen, which may cause the leakage of combustible gas, making the device a safety hazard when in use. At the same time, the burner structure of the existing annealing furnace cannot detect the temperature at the nozzle when in use, so it is not convenient for the operator to control the heating temperature.
