In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Embodiment
[0025] As Figures 1-5 shown, the waste gas burner of the embodiment includes an installation cylinder 1, a fire protection cylinder 2, and a small chamber 3 fixedly arranged between the installation cylinder 1 and the fire protection cylinder 2, and the small chamber 3 is communicated with the fire protection cylinder 2; it also includes a main firing gun 4 passing through the installation cylinder 1 and the fire protection cylinder 2, and the muzzle of the main firing gun 4 is arranged in the fire protection cylinder 2; it also includes an ignition gun 5 passing through the installation cylinder 1 and the small chamber 3, and the muzzle of the ignition gun 5 is arranged in the small chamber 3.
[0026] Through such a design, the ignition gun 5 ignites in the small chamber 3, thereby triggering a large fire in the fire protection cylinder 2. The small chamber 3 isolates the influence brought by the external air flow and improves the ignition success rate.
[0027] Specifically, a protection tube 11 is arranged in the installation cylinder 1, the main firing gun 4 passes through the protection tube 11, and the end of the protection tube 11 is connected to the end of the fire protection cylinder 2.
[0028] Through such a design, the main firing gun 4 can be protected.
[0029] Specifically, it further includes a side plate 6 fixedly connected to the side wall of the protection tube 11. The side plate 6, the protection tube 11, the inner end cover plate 12 of the installation cylinder 1, and the first end cover plate 21 of the fire protection cylinder 2 cooperate to enclose the small chamber 3. The side plate 6 is provided with a through hole 61 for oxygen to enter.
[0030] Through such a design, the formation of the small chamber 3 is ensured; the through hole 61 facilitates the entry of oxygen in the environment to cooperate to reach the condition of igniting a small fire.
[0031] Specifically, the first end cover plate 21 is provided with a fire passing hole 22 for the flame to pass through.

[0035] Specifically, the installation cylinder 1 is provided with an annular side wall 13, and the annular side wall 13 is provided with several first through holes 14.
[0036] Through such a design, since the exhaust gas is a high-temperature gas, several first through holes can reduce the area of the annular side wall 13 so as to reduce the heat absorption area and prevent heat from being transferred to the outside through the installation cylinder 1.
[0037] Specifically, an arc-shaped side wall 7 is clamped between the first end cover plate 21 and the inner end cover plate 12, and the arc-shaped side wall 7 is arranged opposite to the side plate 6.
[0038] Through such a design, the arc-shaped side wall 7 and the side plate 6 cooperate to symmetrically weld and support the fire protection cylinder 2.
[0039] Specifically, several second through holes 71 are provided on the arc-shaped side wall 7.
[0040] Specifically, several air inlets 23 for the exhaust gas to enter are provided on the side wall of the fire protection cylinder 2.
