Specific Embodiments
[0016] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments and drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0017] Please refer to the attached Figure 1-2 , the present utility model provides a fire row burner with a new structure, which includes a heat preservation and heat insulation outer shell 1, a combustion shell 2 and a fire row single-piece assembly 3. The heat preservation and heat insulation outer shell 1 is arranged on the periphery of the combustion shell 2, and a heat insulation area is formed between the heat preservation and heat insulation outer shell and the combustion shell. The air in the heat insulation area is used to reduce the heat loss to the outside, thereby improving the thermal efficiency of the burner. A first ventilation structure 4 is arranged on the shell wall of the heat preservation and heat insulation outer shell 1, and a second ventilation structure 5 is arranged on the shell wall of the combustion shell 2. External air can enter the inside of the combustion shell 2 through the first ventilation structure 4, the heat insulation area and the second ventilation structure 5, so as to input fresh air, ensure sufficient oxygen for combustion, and reduce the emissions of flue gas and nitrogen oxides; in addition, when the outside cold air passes through the heat insulation area, it can bring the heat in the heat insulation area into the combustion shell, avoiding excessive temperature rise of the heat preservation and heat insulation outer shell. The fire row single-piece assembly 3 is arranged at the bottom position of the combustion shell 2, and an ignition needle 6 and an induction needle 7 are arranged at the position of the combustion shell 2 close to the fire row single-piece assembly 3.
[0018] A plurality of profiled heat storage strips 8 are distributed on the shell wall of the combustion shell 2. The second ventilation structure 5 is arranged at the top of the profiled heat storage strip, and the profiled heat storage strip has the effect of storing and retaining heat and reducing heat loss.
[0019] The first ventilation structure 4 is composed of a plurality of heat dissipation holes, and the plurality of heat dissipation holes are evenly distributed on the shell wall of the heat preservation and heat insulation shell, so as to facilitate uniform air intake.
[0020] A first fire viewing structure 9 is provided at a position close to the bottom of the heat preservation and heat insulation shell 1, and a second fire viewing structure 10 is provided at the position of the combustion shell 2 corresponding to the first fire viewing structure. Users or maintenance personnel can observe the combustion condition and flame of the single-fire row component through the first fire viewing structure and the second fire viewing structure.
[0021] A fuel input mechanism for supplying gas to the single-fire row component is provided on the combustion shell 2. The fuel input mechanism includes a pipeline 11 and a solenoid valve 12. The solenoid valve is used to control the on or off of the pipeline. The solenoid valve works according to the induction signal of the induction needle 7. When the induction needle does not sense the flame, the solenoid valve closes the pipeline to avoid gas leakage.
[0022] The single-fire row component 3 is composed of a plurality of fire row pieces arranged side by side at intervals. The fire row pieces arranged at intervals can facilitate the passage of air between the two fire row pieces, ensuring sufficient gas supply to ensure full combustion.
