As shown in Figure 1-2, a kind of burner described in the embodiment of the present invention, including butterfly valve 7, air inlet pipe 6 and gas nozzle 3, described butterfly valve 7 is arranged in the middle part of blast pipe 12, blast pipe 12 is connected with inlet air plenum 9, inlet air plenum upper weld has sealed installing seat 5, stainless steel tube 4 is welded with sealed installing seat 5, stainless steel tube 4 welded top has trouserss 2, form equal pressure chamber 13 after stainless steel tube 4 and sealed installing seat 5 and trouserss 2 welding, inlet air plenum 9 is constituted after stainless steel tube and sealed installing seat 5 welding, it is provided with several air vents in the middle part of sealed installing seat 5, described heating tube 1 lower seal is welded on above sealed installing seat 5, top extends to outside trouserss 2；Trouserss 2 are provided with hurricane globe 14, and fixing welding, air inlet pipe 6 extend at heating tube 1 inner side arc described air inlet pipe 6 with sealed installing seat 5 middle part；Described gas nozzle 3 is located at equal pressure chamber 13 top, gas nozzle 3 afterbody and heating tube 1 and is welded and fixed.It is welded and fixed in the middle part of described sealed installing seat 5 and little fire tube 8, described heating tube 1 top is arc, described trouserss 2 surface is provided with the burner port 11 matching with gas nozzle 3, and described little fire tube 8 position corresponding with hurricane globe 14 is provided with kindling material hole 15.
A kind of burner described in the embodiment of the present invention, the heat radiation producing when heating tube 1 is by flame combustion heats, and heats combustion gas with this.It is multiple in this heating tube 1 that welding is passed through in heated combustion gas again（As 6 or 8, bigger burner can have 10 or more）Uniform gas nozzle 3 sprays at a high speed.On this gas nozzle 3, there is one piece of porous trousers 2；Burner port 11 on trouserss 2 is corresponding one by one with the quantity of gas nozzle 3, position.The effect of this cover is：Form a half-duplex channel between combustion air and combustion gas and air；When combustion air and combustion gas are through trouserss 2, make the combustion air passing through and the combustion gas burner port 11 by specifying simultaneously, force the mixing being formed between two kinds of gases simultaneously, now sprayed from the several burner ports 11 setting because limiting a large amount of gases by burner port 11 footpath, the gas that the flow velocity now spraying is fast, concentration is high carries out burning, the fiery heart turns white, flame is blue it was demonstrated that fuel gas buring is abundant.Little fire tube 8 corresponding place relative with hurricane globe 14 is provided with kindling material hole 15, and when temporary close burner, the fire of little fire tube 8 will not extinguish, and is further continued for burning it is only necessary to the burnt gas switch opening on gas inlet road just can be utilized the kindling material of small fire pipe 8 to be lighted.Its saving of QI exhaustion of little fire tube 8, is almost negligible, and can avoid the complicated processes repeating to light a fire.
Burner is made up of four functional areas：It is gas inlet part respectively；Combustion air supply section；Combustion gas and the Forced Mixing of combustion air；The holding of kindling material.
1st, gas inlet part：It is made up of air inlet pipe 6, heating tube 1, gas nozzle 3.
Concretely：Enter air inlet pipe through the combustion gas of peripheral control valve, throttle valve control along gas circuit, send into heated in the upper end within heating tube, and the burned heating tube 1 of flame heating.Due to the effect of fuel gas source gas air pressure, upper end within heating tube 1 for the combustion gas flows downward, enter multiple uniform gas nozzles 3 small-bore tracheal strips, after through valve spray, formed multiple high-speed and high-temperatures jet flow gas combustion.
2nd, combustion air supply section：Combustion air enters inlet air plenum 9 by blast pipe 12 road through butterfly valve 7, the top of inlet air plenum 9 is the sealed installing seat 5 with multiple holes, combustion air enters equal pressure chamber 13 from the porous of the sealed mounting seat 5 of inlet air plenum 9, and the burner port on trouserss 2 through equal pressure chamber 13 top is sprayed with the combustion gas being sprayed by nozzle simultaneously upwards.
3rd, the Forced Mixing of combustion gas and combustion air, in structure design, there are several uniform burner noz(zle)s, just correspond to have several burner ports on trouserss 2, and the center of nozzle is necessary with the center of burner port coaxial, the upper surface of nozzle must strictly be controlled with the distance of trouserss 2 lower plane, and certain gas is sprayed by nozzle, above the stretchable holes directive on trouserss 2；Combustion air acting on it is also necessary to be ejected by the stretchable holes of trouserss 2 due to aspiration pressure in equal pressure chamber 13 simultaneously.Both gas completes the Forced Mixing of moment when flowing through the upper plane of the burner port to trouserss 2 for the nozzle.To note here is that：
A, there are higher temperature, the moment of ejection because of combustion gas, combustion gas intermolecular distance is greater than the gas molecule spacing of room temperature, therefore increased the degree with other gas mixings；
B, the area because of burner port are less than the area of intake air way, and in the moment flowing out stretchable holes, flow velocity is accelerated, and therefore mixing velocity also can be accelerated therewith；
C, because the area of stretchable holes on trouserss much smaller compared with the area of position any on wind path, close to the blast producing with blower fan, the concentration of therefore mixed gas is higher for the pressure reduction of the air inlet side of stretchable holes and side of giving vent to anger in theory.
For these reasons, compared with other burners are in fuel gas buring, fully performance power is big, it is abundant to burn, and is eventually exhibited as, and in the case of equal vigor, saves combustion gas very prominent for this burner.
4th, kindling material keeps：The combustion gas that little fire tube 8 provides is low pressure, low discharge.Burn always during whole work, the effect of kindling material be provided for work flame, this this burner be used on Chinese dish cooking oven tool particularly important can frequently switch flame, realize larger range of energy-conservation.
