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.
