Utility model content
Its object of the utility model is just to provide a kind of oil pressure-low-pressure air atomizing formula burner, have the advantages that flame rigidity is good, volume heat capacity is high, the thermal output of separate unit product is large, and structural reduction, convenient operation and maintaining, light diesel fuel and heavy oil are applicable to burn.
The technical scheme that realizes above-mentioned purpose and take is, comprises bellows, oil gun, air register, flame holder, air door and igniter, and described oil gun entrance is provided with fuel flow control valve, and oil gun outlet is provided with pressure oil spout nozzle; Described fuel flow control valve and air door are non-coordinated type manual adjustments, are provided with separately adjusting handle or regulating valve stem.
Compared with prior art the utlity model has following advantage.
This device had both been provided with and can have produced by oil pressure the nozzle of atomization, was provided with again the air register that can produce air draught atomization.The two combines, and can make typical machine pressure atomizing burner fuel-oil atmozation pressure significantly reduce, and has significantly improved again the atomization quality of fuel oil, and the burning capacity of right burner is greatly increased.The burner that its performance is obviously better than adopting separately oil pressure mechanical atomization or adopts separately low-pressure air atomizing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure principle schematic front view;
Fig. 2 is this device control principle schematic flow sheet.
The specific embodiment
This device comprises bellows 1, oil gun 8, air register 2, flame holder 3, air door 7 and igniter 5, and as shown in Figure 1, described oil gun 8 entrances are provided with fuel flow control valve 9, and oil gun 8 outlets are provided with pressure oil spout nozzle 4; Described fuel flow control valve 9 is non-coordinated type manual adjustments with air door 7, is provided with separately adjusting handle or regulating valve stem.
Described burner outlet setting has the shellring shape spiral-flow type air register 2 of autonomous channel, and the angle of ground floor air register swirl vane is 30 °, and the second layer is 15 °, and the 3rd layer is 5 °.
Bluff body flame holder 3 of described air register 2 center configuration, oil gun 8 nozzles 4 stretch into and revolve mouth through flame holder 3 centre bores.
This device is mainly made up of bellows, oil gun, air register, flame holder, fuel flow control valve, air door and igniter, after the air stream impact atomization that fuel oil sprays under certain pressure through oil gun and flowed out by air register, form mist of oil air mixture, after incendiary source is lighted, realize normal combustion.
At oil gun entrance, a flow control valve is installed, can the oil burning jet output of gas gun is realized continuously and being regulated by this valve; In oil gun outlet, a simple-type pressure oil spout nozzle is installed, under certain pressure effect, can have been realized the primary atomization of fuel oil.
The shellring shape spiral-flow type air register burner outlet being provided with autonomous channel, the angle of ground floor air register swirl vane is 30 °, and the second layer is 15 °, and the 3rd layer is 5 °, and the wind of air register ejection can be implemented secondary-atomizing to mist of oil.
At bluff body flame holder of air register center configuration, oil gun nozzle stretches into and revolves mouth through flame holder centre bore.
Fuel flow control valve and air door are non-coordinated type manual adjustments, are provided with separately adjusting handle or regulating valve stem, arrange after servo governor motion on above-mentioned valve, can realize automatic linkage or the adjusting of fuel tap and air door.
1 burner structure feature:
It is as follows that this type of burner is different from other types oil burner primary structure feature:
A) be provided with the oil gun with fuel flow control valve and simple-type pressure fuel nozzle;
B) be provided with the shellring shape spiral-flow type air register with autonomous channel, the swirl vane angles in each circular passage reduces from inside to outside gradually;
C) generally, fuel flow control valve and air door can separately carry out manual continous way adjusting, and servo governor motion also can be set on valve and air door, implement automatic linkage and regulate.
2 operation principles
There is the fuel oil of certain pressure after flow control valve is implemented Flow-rate adjustment, spray into and revolve the existing primary atomization of cause for gossip, then carry out secondary-atomizing by air register internal layer air-flow, and realize after the abundant mixing of mist of oil and air, through lighting postignition burning.The setting of flame holder, can make high temperature gases recirculating, with smooth combustion flame.
The mechanical atomization effect that the fuel-oil atmozation of this type of burner is produced by nozzle and the percussion of low-pressure air are achieved.Under underload, fuel-oil atmozation effect mainly comes from low-pressure air air-flow; Under high load capacity, fuel-oil atmozation effect mainly comes from oil pressure.The two supplements mutually, can under compared with low oil pressure power (with respect to mechanical pressure atomization) and lower air pressure (with respect to high-pressure medium atomization), realize the good atomization of fuel oil in load regulation range, the later stage that the second layer of air register and the 3rd layer of air-flow can be realized fuel fully burns and flame is played to envelope effect.
