Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment, the utility model and its Advantageous Effects are carried out detailed further
Describe in detail bright.
Referring to Fig. 1 ~ Fig. 2, low-caloricity gas burner includes combustion chamber 2, air blast 5 and flame jet 3, combustion gas and enters
Mouth 6, air inlet 7, combustion chamber 2 is hollow-core construction, and flame jet 3 is located at the head of combustion chamber 2, air inlet 7 and air blast 5 phase
Even；It is characterized in that：Low-caloricity gas burner also includes the premixer 1 of hollow cylinder structure, and combustion chamber 2 is arranged at premixer
In 1, fuel gas inlet 6 and air inlet 7 distinguish the tangentially tangent setting with premixer 1 of premixer 1 bottom, combustion chamber 2 afterbody
It is communicated with the fire power regulator of premixer 1.Wherein, fuel gas inlet 6 and air inlet 7 are located at same circumferential position, Liang Zhecheng
