Description
Technical field
The present invention relates to a kind of burner nozzle, be meant a kind of burner nozzle that heavy and inferior fuel fully can be atomized especially.
Background technology
Burner is made up of fuel nozzle and air register.Burner nozzle is the critical component of industrial kiln burner, and fuel nozzle is placed on the air register axial line, and fuel fog is changed into thin dripping, and sprays in the combustion chamber with certain angle of flare (also claiming atomizing angle), mixes the postignition burning mutually with the air that air register is sent into.Existing fuel nozzle mainly contains two kinds of pressure atomization and twins.The pressure atomization fuel nozzle is made up of splitter, spinning disk and atomizing piece.During use, fuel generally produces high speed rotary motion in spinning disk, through the centre bore ejection, is broken into thin dripping under action of centrifugal force, and the fuel droplet average diameter after atomizing is many below 100 microns.What pressure atomization was current is to adopt single fluid engine driven supercharging formula, progressively withdraws from the market because of atomizing effect is difficult to meet the demands.The twin fuel nozzle then utilizes steam or compressed air as atomizing medium, utilizes the negative-pressure siphon of adjusting the flowing gas generation that fuel is quickened and broken atomizing.As seen, twin promptly obviously is better than single fluid engine driven supercharging formula on principle, wherein use the bifurcation type fuel nozzle of steam as atomizing medium, gain the name because of steam channel becomes bifurcation shape oblique with fuel channel, it has the advantage that load regulation range is big, steam consumption is few.But market proves that also there is greatly room for improvement in twin.
Summary of the invention
The purpose of this invention is to provide a kind of two-fluid burner nozzle, the advantage of comprehensive single fluid engine driven supercharging formula and air-flow siphon and the explosion of double-current body fluid bubble transformation, produce double fluid and simultaneously around " cyclone " formula atomizing type of center high-speed rotary, with guarantee the fuel droplet diameter 30 microns following average diameters about 5 microns.
Designed a kind of burner nozzle according to above-mentioned purpose, comprise nozzle base, in this base with on the axis parallel direction, offer inlet channel and fuel channel, the all sensible vortex chamber that mixes of described inlet channel and fuel channel, should mix vortex chamber and spout connection, described nozzle base is a cylinder, has a counterbore at the front end edge axis of this nozzle base, and this counterbore is parallel with the fuel channel of straight-through front end and connect with inlet channel; In this counterbore, be shelved with a cross section and be the blade of T-shaped rotary body, the bottom of this blade is a hollow tube, and the disc on blade top is shelved on counterbore along last and compressed and locate along the edge by the cap of spraying nozzle inwall, and the chamber that constitutes vertically between this blade and cap of spraying nozzle is described mixed vortex chamber; The described cap of spraying nozzle enclosure is at the front end of nozzle base, and spout is opened in the top of cap of spraying nozzle, is provided with one and regulates core in spout, is spirally connected in the tup shape bottom of this adjusting core and the inwall of blade.
Wherein, offer an annular fuel channel slot at the front end of described nozzle base, this fuel channel groove is vertical with fuel channel and directly be communicated with.On the disc on described blade top, have the through hole that mates and be communicated with the fuel channel groove vertically, also having the oblique hole that connects with described counterbore on disc, is matched in clearance between blade lower end and the counterbore, and the chamber that this gap constitutes is the inlet channel chamber that is communicated with inlet channel.Be evenly equipped with the groove that becomes 30～45 degree angles with circumferential normal direction on the disc upper surface of described blade top, this groove connects the edge and the hollow hole of disc.Groove on the disc upper surface of described blade top is a linear groove, and this groove is provided with in pairs, and one is communicated with the fuel channel groove in edge, and adjacent another is communicated with oblique hole and the rest may be inferred in edge.Be provided with the clamp nut that carries out shutoff to along the lower port of axis hollow in the lower end of described blade, same week of the joint portion of this blade bottom and blade top disc upwards, also be provided with the cyclonic current through hole that runs through the blade lower sides equably.Described cyclonic current through hole is oblique hole, and this through hole becomes 30～45 degree angles with circumferential normal direction, and this through hole is provided with in pairs.In addition, described spout is outside bell mouth shape, and the angle of bell-mouthed sidewall and bottom surface is 60～120 degree.The top that described adjusting core cooperates with spout is for also being the adjusting core top flat of T-shaped rotary body, and the bottom shape of the card of this T-shaped rotary body and described bell-mouthed shape adapt.
The present invention is simple in structure, compact, and parts are few, assemble, safeguard easily, and parts is metalwork, suitable hot environment, the high particle-liquid fuel of many impurity such as suitable corrosivity alcohol ether basic ring guarantor's liquid fuel and high viscosity environment protective emulsive heavy oil.During use, the inclined hole and the oblique slot that are provided with by nozzle interior lead, band pressure gas stream and fuel stream is all sprayed from spout in rotary manner, the fluid of ejection is in the T-shaped rotary body guiding of regulating the core top and by the advantage of two-fluid siphon, form " cyclone " formula atomizing type that central negative pressure and double fluid rotate at a high speed around the center simultaneously on the axis before spout, under the pressure that forms at a high speed, make the intensive microbubble explosion in the gas-liquid DL stream, the diameter that has guaranteed big footpath fuel droplet effectively is below 30 even 10 microns, it is more abundant to make liquid fuel mix with combustion air, balanced, improve flammable liquid particulate and airborne oxygen contact area greatly, especially as jet-propelled sonic boom conflagration, substance combustion is thorough, the bright and limpid bright temperature height of flame, liquid gas mixed equilibrium, the thermal efficiency and heat utilization efficiency height, emission of substance is few, and environmental protection and economic benefit are splendid.
