Description

Low-nitrogen oxygen combustor for tunnel kiln Technical Field The application relates to the field of tunnel kiln burners, in particular to a low-nitrogen-oxygen burner for a tunnel kiln. Background The tunnel kiln is a kiln which is built by refractory materials, heat-insulating materials and building materials and internally provided with kiln cars, and is modern thermal equipment. The tunnel kiln is widely applied to the roasting production of ceramic products and also has application in the metallurgical industries such as abrasive materials and the like. The existing tunnel kiln comprises a kiln wall and a plurality of burners, the burners penetrate through the kiln wall, one ends of the burners are connected with a wire pipe, the other ends of the burners are provided with spray heads, the wire pipe is located outside the tunnel kiln, the spray heads are located in the tunnel kiln, the wire pipe is used for providing air and fuel for the burners, flame is sprayed out of the spray heads after the burners ignite the fuel, and therefore the temperature in the tunnel kiln is improved, and workpieces in the tunnel kiln are heated. The related technical scheme has the defects that the temperature in the tunnel kiln has a larger influence on the forming quality of the workpiece, and the difficulty of controlling the temperature of the workpiece in the tunnel kiln by a user is larger. Disclosure of utility model In order to facilitate the control of the heating temperature of a workpiece in a tunnel kiln by a user, the application provides a low-nitrogen oxygen burner for the tunnel kiln. The application provides a low-nitrogen oxygen burner for a tunnel kiln, which adopts the following technical scheme: the utility model provides a low nitrogen oxygen combustor for tunnel cave, includes kiln wall, fixed section of thick bamboo, combustor and fixed establishment, has seted up the through-hole on the kiln wall, and fixed section of thick bamboo inserts in the through-hole and is fixed with the kiln wall, and the combustor inserts in the fixed section of thick bamboo, combustor and fixed section of thick bamboo sliding connection, fixed establishment setting are on kiln wall outer wall, and fixed establishment is used for fixed combustor.
