Embodiment 1

[0015] Such as figure 1 The intelligent natural gas burner that can avoid backfire phenomenon includes a burner body 1; an air inlet port 2 is arranged on the burner body 1, and the air inlet port 2 is connected with a natural gas mixing chamber 3 , the natural gas mixing chamber 3 is respectively connected with a natural gas inlet pipe 4 and an atmospheric air inlet pipe 5; The end portions 301 are opposite to each other at the second end portion 302, the inner diameter of the natural gas mixing chamber 3 gradually decreases in the direction in which the first end portion 301 extends toward the second end portion 302; the first end portion of the natural gas mixing chamber 3 301 is provided with a pipe diameter control device, which includes a control end plate 6 extending radially along the natural gas mixing chamber, and a support end plate 7 arranged on the inner wall of the natural gas mixing chamber 3. The support end plate 7 adopts an annular structure, the control end...

Embodiment 2

[0018] As an improvement of the present invention, a plurality of spoiler pipes 9 are arranged on the end surface of the control end plate 6 relative to the first end 301 of the natural gas mixing chamber 3, and each spoiler pipe 9 includes The first end portion 901 that controls the position of the axial center of the end plate 6 , and the second end portion 902 that extends to the side portion of the control end plate 6 along the radial direction of the control end plate 6 .

[0019] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0021] As an improvement of the present invention, the end surface of the control end plate 6 relative to the second end 301 of the natural gas mixing chamber 3 adopts a curved surface structure bent toward the second end 302; The end surface of the second end portion 302 of the mixing chamber 3 extends obliquely downward.

[0022] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses an intelligent natural gas combustion furnace capable of avoiding the backfire phenomenon. The intelligent natural gas combustion furnace comprises a combustion furnace body. The combustion furnace body is provided with a gas input end opening. The gas input end opening is connected with a natural gas mixing chamber. The natural gas mixing chamber comprises a first end portion connected to the gas input end opening, and a second end portion mutually opposite to the first end portion. The first end portion of the natural gas mixing chamber is provided with a pipe diameter control device which comprises a control end plate and a supporting end plate. A ring-shaped structure is adopted in the supporting end plate. The control end plate is arranged between the supporting end plate and the first end portion of the natural gas mixing chamber. The control end plate is connected to the supporting end plate through multiple connecting rod pieces parallel to the axial direction of the natural gas mixing chamber. The intelligent natural gas combustion furnace capable of avoiding the backfire phenomenon can effectively avoid generation of the backfire phenomenon in theworking process of the natural gas combustion furnace, and therefore use safety of the combustion furnace is further guaranteed.

Description

technical field [0001] The invention relates to the field of thermal energy engineering, in particular to an intelligent natural gas combustion furnace capable of avoiding backfire phenomenon. Background technique [0002] Natural gas combustion furnace is one of the more common combustion equipment in industrial processing. Backfire phenomenon often occurs in the existing natural gas combustion furnace during actual use; the above phenomenon not only makes it difficult to guarantee the working performance of the combustion furnace, but even causes safety accidents in severe cases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a natural gas combustion furnace, which can effectively avoid backfire phenomenon during the working process, so that the safety of the combustion furnace can be further guaranteed. [0004] In order to solve the above-mentioned technical problems, the present invention relates to an int...
