Burner noz(zle) 10 includes premix component 12 and fuel assembly 15, premixes component 12 and fuel assembly 15 is connected with each other,
It premixes component 12 and is used for mixed combustible gas body and combustion-supporting gas, and form mixed firinor fuel burning gas, and be oriented to and be mixed and burned gas extremely
Fuel assembly 15, fuel assembly 15 is for spraying above-mentioned mixed firinor fuel burning gas.
Wherein, fuel assembly 15 includes gas inlet pipe 151, burn generator tube 152 and gaseous mixture outlet end cap 154, in advance
Mixed component 12 includes premix casing 121 and helps gas inlet pipe 122；
It premixes casing 121 to be used to enter for combustion-supporting gas, there is flame export 1521 to be used for for one end of burning generator tube 152
It is sprayed for being mixed and burned gas, the other end is connected to gas inlet pipe 122 is helped, and helps gas inlet pipe 122 for for combustion-supporting gas
Into；
The one end of gas inlet pipe 151 is gas outlet section 1511, and offering combustion gas in gas outlet section 1511 goes out
Gas port 1512, for for fuel gas through gas outlet 1512 flow out gas inlet pipe 151, gas inlet pipe 151 with it is combustion-supporting
Gas air inlet pipe 122 connects, and gas outlet section 1511 is set in burning generator tube 152；
One end of premix casing 121 is set in gas inlet pipe 151, and entangles gas outlet section 1511, another end opening
For mixed gas outlet 1211, mixed gas outlet 1211 is used to enter burning generator tube 152 for being mixed and burned gas, also, premixes
Combustion supporting air inlets 1212 are offered on the peripheral wall of casing 121, Combustion supporting air inlets 1212 are used to enter premix casing for combustion-supporting gas
121；
Gaseous mixture outlet end cap 154 is connected to gas outlet section 1511, and is located at mixed gas outlet 1211, and gaseous mixture goes out
The edge of gas end cap 154 and 1211 inner wall of mixed gas outlet are spaced, and form gaseous mixture gas outlet 1541, gaseous mixture outlet
End cap 154 is for limiting combustion-supporting gas and fuel gas in premix casing 121；
When burner noz(zle) 10 uses：
Fuel gas is entered by gas inlet pipe 151, and is entered in premix casing 121 by gas outlet 1512, combustion-supporting
Gas enters by helping gas inlet pipe 122 to enter, and by Combustion supporting air inlets 1212 in premix casing 121, combustion-supporting gas and flammable
Gas in being mixed in premix casing 121 and forming mixed firinor fuel burning gas, be mixed and burned gas and by gaseous mixture gas outlet 1541 into
Enter to burn generator tube 152, then is sprayed by flame export 1521, in above process, is sprayed again after first being mixed due to combustion-supporting gas
Burning, burner noz(zle) 10 can ensure the mixed effect of combustion-supporting gas and fuel gas, so that fuel gas can be abundant
Burning, and have the characteristics that energy conservation and environmental protection.
Further, premix component 12 further includes premix demarcation strip 123, and premix demarcation strip 123 is set in gas outlet section
1511, and the edge of demarcation strip 123 and the inner wall of premix casing 121 are premixed there are gap, Combustion supporting air inlets 1212 and combustion gas go out
Gas port 1512 is oppositely arranged, and may be contained within premix 123 side of demarcation strip or both sides, is distinguished in combustion-supporting gas and fuel gas
When being entered in premix casing 121 by Combustion supporting air inlets 1212 and gas outlet 1512, premix demarcation strip 123 will premix casing
121 inner space separates, and to form multistage premix chamber, further increases the mixing effect of combustion-supporting gas and fuel gas
Fruit is needed further, it is to be appreciated that above-mentioned premix demarcation strip 123 may be multiple with adapting to the asynchronous mixing of quantity combusted
It asks, such as three spaced premix demarcation strips 123, to form four continuous premix chambers in premix casing 121, makes
Combustion-supporting gas in the case of larger quantity combusted and fuel gas can also be sufficiently mixed, to ensure corresponding combustion efficiency.
Further, demarcation strip 123 is premixed, premix demarcation strip 123 is flexibly connected with gas outlet section 1511, and being capable of edge
The axial movement of gas outlet section 1511 to block or partial occlusion gas outlet 1512, and then is completed to adjust by combustion gas
Gas outlet 1512 enters the air inflow and intake velocity of the fuel gas of premix casing 121, and then ensures that fuel gas has
One preferable intake velocity and air inflow improve the mixed effect of fuel gas and combustion-supporting gas, ensure combustion efficiency, favorably
In burning scene that is energy saving, and can adapt to different, the suitability of burner noz(zle) 10 is improved.
It is understood that premix demarcation strip 123 can pass through rotation in gas outlet section 1511 by thread set
Demarcation strip 123 is premixed to make premix demarcation strip 123 be moved along the axial direction of gas outlet section 1511, can also be directly set in
Gas outlet section 1511, can also be set in gas outlet section 1511 by way of sliding rail and sliding block, and the present embodiment is simultaneously unlimited
Movable connection method between system premix demarcation strip 123 and gas outlet section 1511.
It should be noted that the conical surface of the circumferential surface of premix demarcation strip 123, it is round table-like to premix demarcation strip 123 in other words, and
The larger one end end face of bore of demarcation strip 123 is premixed towards mixed gas outlet 1211, is existed with reducing combustion-supporting gas and fuel gas
The generation vortex in casing 121 is premixed, the mixed effect of combustion-supporting gas and fuel gas is further increased.
Please continue to refer to Fig. 2, premix component 12 further includes combustion-supporting gas regulating part 124, and combustion-supporting gas regulating part 124 is flexibly connected
