The air feed spray-hole that this burner is designed, its arrangement is distributed on the barrel of cartridge type combustion chamber in an orderly manner, its injection direction is, or with left-handed, or with dextrorotation, or with entad, and with the tube aperture in a certain angle, bottom surface of this chamber.All this holes are slightly larger than the aperture that distributes in the barrel Lower Half in the aperture that the barrel first half distributes.This pore diameter range is advisable at φ 3~6mm.Its injection direction is advisable at 0~70 degree with the angular range of tube certain angle that the bottom surface was.
The air feed interlayer that this burner is designed on its limit that turns edge outside the barrel top of cartridge type combustion chamber, promptly on the top of this interlayer, is provided with and arranges orderly top blowhole.The pore diameter range in all this holes also is advisable at φ 3~6mm, its injection direction can with the tube chamber central axes of this chamber, also entad angle ground points to the tube chamber central shaft of this chamber.This interlayer over top can also be provided with the closing in type head-shield that keeps out the wind.In the bottom interlayer of this interlayer, can be provided with and arrange orderly guide vane, all this sheets or left-handed or be arranged in dextrorsely on the base plate face of bottom interlayer.
The fuel feed pump that this burner is designed, itself and the high-order oil feeding reservoirs of normal pressure are connected, the air feed spray-hole that the barrel place of the combustion chamber of its fuel-displaced mouth of pipe below is provided with, it is that 1~2mm is advisable that the distance of all holes from the tube bottom surface of this chamber arranged at its end, and the oil spilling hole of all holes when can be used as ignition operation arranged at this end.The bore of the fuel-displaced mouth of pipe of this fuel feed pump is advisable at φ 3~10mm, its from the combustion chamber the tube bottom surface suitable height distance at 1/5~1/10 Room height.
The umbrella that keeps out the wind that this burner is designed, it can be diconical, also can be single taper.
Oil burner of the present utility model, its enforcement further describes it in conjunction with the accompanying drawings.Model of the present utility model and specification not only are confined to present embodiment.As shown in the figure:
Fig. 1 partly cuts open schematic diagram for the structure of oil burner.Have among Fig. 1: combustion chamber 1, air feed interlayer 2, bottom interlayer 3, air feed spray-hole 4, top blowhole 5, oil spilling hole 6, fuel feed pump 7, control fuel tap 8, oil inlet pipe 9, the umbrella 10 that keeps out the wind, the head-shield 11 that keeps out the wind, oil spill pipe 12, guide vane 13.
Fig. 2 partly cuts open schematic diagram (the A-A view of Fig. 1) for the plan structure of oil burner.Have among Fig. 2: bottom interlayer 3, fuel feed pump 7, control fuel tap 8, blast pipe 9, the umbrella 10 that keeps out the wind, the head-shield 11 that keeps out the wind, oil spill pipe 12, guide vane 13.
This burner of making, its combustion chamber 1 is made by the 3mm steel plate, the thickness of air feed interlayer 2 and bottom interlayer 3 all is 40mm, air feed spray-hole 4 is φ 4mm, and its left-handed injection direction is 45 degree with tube bottom surface angle, and fuel feed pump 7 is in the tube chamber that enters the combustion chamber apart from tube 50mm place, bottom surface, the bore of this pipe 7 is φ 6mm, by control fuel tap 8 control oil inlet quantities, oil spill pipe 12 is located on the outer side plate of bottom interlayer 3, does not establish valve on this pipe 12 with emptying form discharging oil spilling when lighting a fire.
The combustion process of this burner: at first open control fuel tap 8, fuel oil (diesel oil) flows into the tube chamber of combustion chamber by fuel feed pump 7, generally only there is the oil reservoir of 1mm this bottom, chamber, unnecessary oil plant can flow into by the minimum row's of barrel air feed spray-hole 4 (being spout hole 6) in the interlayer 3 of bottom and flow out outside the burner through oil spill pipe 12, and then avoided trapped fuel too much, and phenomenon is burnt in the prominent detonation that causes, makes the burning security of operation.Place in 1 chamber, combustion chamber with the oily cotton yarn of lighting of being stained with again, open blower fan then, make air quantity enter bottom interlayer 3 and air feed interlayer 2 from blast pipe 9 slowly.Combustion-supporting like this and help the atomizing wind in air feed spray-hole 4 is spurted into a chamber, because left-handed air feed spray-hole 4 sprays the air quantity with certain injection direction and dynamics, can make oil plant in tube chamber, chamber, stop DL and sufficient combustion through the umbrella 10 that keeps out the wind again oil plant and the abundant mixed aerosol of air.This burner is provided with and arranges orderly top blowhole 5 also at the top of air feed interlayer 2, the tube chamber central axes of the injection direction in this wind hole 5 and this chamber 1.The wind that blows out through this hole 5, again through the keep out the wind guiding of head-shield 11 of closing in type, it is combustion-supporting that the mist of oil of burning is carried out the secondary oxygen supply, makes burning more abundant, so that do not have black smoke and produce.
Burner of the present utility model, its advantage is: have the DL effect owing to designed The appropriate location of air feed spray-hole and the oil-feed mouth of pipe makes oil, the abundant mixed aerosol of gas reach burning Sufficient effect. Owing to designed oil spill pipe and the oil spilling hole of emptying, made the combustion chamber internal memory incessantly Excessive oil produces the blast combustion phenomena when having avoided burning, guarantee the operation of this burner combustion Safe and reliable. This device is rational in infrastructure, and safety simple to operate is easy to maintenance, and it is low to consume energy, heating Amount is high, is a kind of ideal burning equipment that is applicable to various stove and accessorys.
