Abstract
The utility model belongs to an oil and gas combined burner used for fuel gas (gas for oil refining and chemical industry) and fuel oil class (fuel oil). When gas is burnt, a fuel gas acceleration nozzle is arranged, and a thrice automatic air distribution duct is matched. When fuel oil is burnt, an oil and gas inner mixed atomizer system for pressurization and acceleration is utilized, and atomized oil drips after sprayed meet tertiary combustion supporting wind to obtain sufficient combustion. The utility model has compact structure, powerful flame when fuel gas is burnt, favorable heat effect, four times of atomization when fuel oil is burnt, fine atomized granules, high heat value, wide range of applicable fuel and convenient operation.
Description
The present invention relates to burner, be specifically related to the burner of combustion of liquid fuel and/or gaseous fuel.
Chinese patent 93229748.X disclosed " spraying burner " distributes valve seat, petroleum pipeline by oily vapour, steam transmitting pipe, the oil gas mixing nozzle, air register wind oil cover is formed, before oily vapour mixing nozzle, be provided with oily vapour hybrid chamber, magnet, the oil magnetization blender that oily vapour spray-hole is formed, blender peripheral hardware air register, the advantage of this device is a secondary-atomizing, magnetization, but because the spray chamber structure is unreasonable, atomizing effect is still not good enough, and air distribution mechanism complexity is unsuitable for Large-scale Heater and forces air distribution control.
The purpose of this utility model is to improve the structure that atomizes, and improves atomizing effect, transforms air feed system, makes full combustion of fuel and stable, satisfies the needs of large-scale technology heating furnace associating or independent combustion fuel oil and/or fuel gas.
Realize that solution of the present utility model is the perforate that slopes inwardly of the steam hole (16) of oil gas nozzle (10), spray chamber (11) hollow cavity is established a trunnion undergauge, the spray orifice (18) of oil gas nozzle (14) outwards is the radiation perforate, form an air channel (19) between casing air (9) and the fuel oil sleeve pipe, gas nozzle (12) endoporus is tapered.Be positioned at atomizer (14) outside at cylindrical shell (6) front interior cavity and be provided with secondary fan housing (13).
The included angle A of symmetrical steam hole (16) center line of above-mentioned oil gas nozzle (10) is 40 °～50 °, intersects with the fuel oil that sprays into when steam is sprayed into, and sends forth and atomized fuel.
Above-mentioned spray chamber (11) inner chamber is established a trunnion undergauge, and its undergauge (diameter) is than for d1: d2=1.5～3, and the trunnion undergauge is accelerated steam and fogging oil drip speed, impels both to mix better and atomizes.
The included angle B of spray orifice (18) center line of above-mentioned oil gas nozzle (14) and the center line of spray chamber (11) is 22 °～26 °, and the atomized fuel of ejection is disperseed more, avoids overlapping.
Above-mentioned gas nozzle (12) endoporus is tapered.Tapering is 1: 20～30, along the combustion gas circulating direction, dwindles internal diameter gradually, to improve the combustion gas spouting velocity.
Above-mentioned secondary fan housing (13) is a tapered cylinder shape, and its major part is fixed on cylindrical shell (6) inwall, and the microcephaly is positioned at the place ahead of atomizer (12).
The utility model has the advantages that and strengthen the fuel-oil atmozation structure, fuel-oil atmozation is thinner, more even, and under three grades of air distribution effects, fuel oil energy is abundant, burn steadily.During fuel gas buring, because the I and II air distribution makes air more can fully mix with combustion gas.Make it abundant burning under three grades of air distribution effects, this burner can satisfy large-scale technology heating furnace associating or use the needs of fuel oil or fuel gas separately.The fuel oil and the fuel gas that can adapt to heterogeneity, different pressures use, and also can adapt to the pressure air distribution control of combustion air preheating.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an oil gas nozzle arrangements schematic diagram.
Fig. 3 is the spray chamber structural representation.
Fig. 4 is the atomizing nozzle structure schematic diagram.
Fig. 5 is the gas nozzle structural representation.
Oil vapour storehouse (2) is fixed on base (5) outside, oil vapour storehouse (2) is provided with fuel filler (20) and steam inlet (21), fuel pipe (3) insert in the bottom, oily vapour storehouse (2) and with fuel filler (20) UNICOM, the outside that steam pipe (4) is enclosed within fuel pipe (3) insert top, oily vapour storehouse and with steam inlet (21) UNICOM, another one of fuel pipe (3) connects firmly oil gas nozzle (10), the cylindrical of oil gas nozzle (10) is near steam pipe (4) front inner wall, spray chamber is fixed on steam pipe (4) front end outer wall, atomizer (14) is fixed on spray chamber (11) front end, casing air (9) is enclosed within spray chamber (11) and fuel pipe (3) outer wall, form one time the air channel, gas sleeve (8) is enclosed within the outer wall of casing air (9), be fixed on base (5) inboard, casing air (9) connects firmly with centring ring (7) with the rear end of gas sleeve (9).Front end connects firmly gas nozzle (12), and Gas Pipe (1) UNICOM is in gas sleeve (8) wall.Cylindrical shell (6) connects firmly the inboard in base (5).Secondary fan housing (13) is fixed on the inner chamber of cylindrical shell (6), and its air outlet position is in the place ahead of atomizer (14), has many fresh air inlets (15) on the cylindrical shell (6).The included angle A of steam hole (16) center line of oil gas nozzle (10) and nozzle opening (17) center line is 50 °, spray chamber (11) inner chamber trunnion undergauge ratio is 2: 1, the included angle B of spray orifice (18) center line of oil gas nozzle (14) and the center line of spray chamber (11) is 24 °, gas nozzle (12) endoporus is tapered, and tapering is 1: 20.
During this burner combustion, fuel oil is disperseed, atomizes by the steam of steam hole (16) ejection through nozzle opening (17) ejection of oily vapour nozzle (10).Owing to be provided with the trunnion undergauge in the middle of the spray chamber, impel steam and fogging oil drip speed to increase, it is fierce to mix, further increase atomizing effect, atomizer (14) is gone up spray orifice (18) and is the radiation perforate, after atomizing oil droplet and the steam ejection, the atomizing oil droplet more disperses with tiny, with three grades of mixed effect ideals of air, burning is complete, flame stabilization.
When Device in Gas is burnt, gas sprays through gas nozzle (12), because nozzle bore has certain taper, gas speed increases, a combustion air that comes out by an air channel (19) at the inner lane of gas nozzle (12), the secondary combustion air that between cylindrical shell (6) and gas sleeve (8), comes out, and three combustion airs that between cylindrical shell (12) and secondary fan housing, come out.One, two, three combustion air fully mixes, atomizes, burns with Device in Gas and fogging oil.
