Embodiment Construction

[0014] In the present invention, as shown in the accompanying drawings, a rotatable sleeve 2 is covered in the combustion tube 1 of the tube type high-speed burner used in the heat treatment furnace. The sleeve has air intake holes with the same size and orientation as the combustion tube, and the air flows into the combustion tube through these small holes to mix with natural gas and burn.

[0015] The amount of air intake is controlled by adjusting the size of the overlapping portion of the air intake hole (on the sleeve) and the air intake port (on the combustion cylinder). Therefore, there should be a corresponding transmission mechanism matched with the sleeve, so that the sleeve can rotate relative to the combustion cylinder, so as to realize the opening and closing of the two holes.

[0016] It comprises handle 8, crank 6, connecting rod 5, and handle is connected on the rotating pin 7 of crank, and the other end of crank is movably connected with connecting rod 5, and ...

Abstract

The invention provides a high-rate burner capable of adjusting the air inlet speed in order to solve the problem that the existing burner is incapable of accurately adjusting the mixing ratio between natural gas and air. A rotatable sleeve is sleeved outside a combustion cylinder; air inlets corresponding to the positions of the air inlets on the combustion cylinder are formed on the sleeve; and a driving mechanism capable of rotating the sleeve to adjust the size of air channels is connected to the sleeve. The invention can effectively improve the situation about the mixed combustion of natural gas and air under various conditions of air flow and achieve the stable combustion no matter what the air flow is, thus guaranteeing the quality stability of heat treatment products.

Description

technical field [0001] The invention relates to the field of gas industrial furnaces, in particular to burners for gas industrial furnaces. Background technique [0002] The barrel-type high-speed burner used in the existing heat treatment furnace has a structure including a combustion barrel, natural gas and air inlets. When in use, the flow, size and ratio of the two are controlled by the natural gas valve and the valve installed on the air pipeline, but the speed at which the air enters cannot be adjusted. When using this kind of burner, since the air cannot effectively adjust its speed after entering the combustion tube, it is impossible to accurately adjust the mixing ratio of natural gas and air in the combustion tube to achieve fine control, especially when the burner is working at low load. . Contents of the invention [0003] The purpose of this invention is to solve the problem that the existing burners cannot accurately adjust the mixing ratio of natural gas a...
