The invention relates to a technique of sputtering, in particular liquids, spray agent. The nozzle may and, when baking bread, when heated and hardening of workpieces and products in metallurgy, household heating equipment, etc. where there is a problem of high-quality liquid fuel combustion at small expense. It can also be used in other processes where the problem occurs quality spraying small quantities of liquids, for example in drying milk paint products, spraying plants.

Known nozzle, comprising a housing and a sleeve coaxially mounted therein to form between them an annular fuel cracks and internal and peripheral channels for supplying the atomizer connected to Solovay apparatus, made in the form of an annular series of narrow slots that are offset in the circumferential direction in adjacent rows, wherein the longitudinal axis of the slots of the outer row are oriented towards the axis of the nozzle, and an internal number from the axis of the nozzle (see ed. mon. USSR N 876179, F 23 D 11/12).

The disadvantage of this technical solution is that two independent flow atomizer have a twist in different directions around the axis of the nozzle. This leads to rapid mixing of the flows between itself and the collapse of the torch in the axial zone of the flow at low intensivnostei, is the creation of a nozzle, ensuring its stable operation, high-quality atomization of fuel and getting a wide symmetrical torch at small expenditure of fuel and removal of built-up edge on the peripheral end part.

The technical result achieved by implementation of the proposed nozzle, preventing adhesion of droplets of fuel to the outer surface of the nozzle through the use of the forces of ejection.

The solution of this problem is achieved by the fact that in the nozzle, comprising a housing with a conical end surface of the sleeve is coaxially installed with the formation of the inner channel for supplying fluid from the annular inlet nozzle and a peripheral channel for supplying nozzle connected to Solovay apparatus, made in the form of an annular series of narrow slits, with an annular nozzle formed between the surfaces of the sleeves, made in the exit area of the conical forming intersecting the axis of the housing before the weekend cut nozzle apparatus, the slot of the slot is made in the case, and their output sections located on the end of the conical surface, forming a which intersects the longitudinal axis of the housing at or behind you is/P> From the prototype of the claimed invention differs in that slot of the slot is made in the case, their output sections located on the end of the conical surface forming which intersects the longitudinal axis of the housing at or beyond the outlet slice nozzle apparatus, and the angle of its inclination to the axis performed in excess of 40o.

This injector is designed to work at low costs raspisivaem fluid and collectively, the above characteristics are provided by the solution of the problem.

Namely, the execution in the case of narrow slits, the output sections which are located on the end of a tapered surface allows the liquid fuel flowing thin film of an annular outlet nozzle, to interact on a tangent with jets of spray emanating from the slit of the slit nozzle of the apparatus, with the formation of a wide torch. When applying the spray agent only in the peripheral channel offers the possibility of reducing fuel consumption with a simultaneous increase in the rate of discharge from the annular outlet nozzle by reducing its diameter. By reducing the size of the nozzle and the spray reduced giliausio agent).

Execution end conical surface forming which intersects the longitudinal axis of the hull damage or output slice nozzle apparatus, and the angle of its inclination to the axis performed in excess of 40oeliminates coking of the nozzles, as at an inclination of more than 40obuild-up of liquid drops on the outer wall of the nozzle does not occur. With increasing angle between the generatrix of the outer peripheral end surface with the axis of the nozzle 40oand more efficiency breakdown drops of fuel from the surface by the ejection of the spray agent increases. This eliminates the possibility of penetration of the drops through the gap between the jets of the spray agent to the outer cylindrical wall of the nozzle and their adhesion to the wall.

Such use of the outer end of the conical surface of the nozzle stabilizes the dispersion and improves its quality in a number of technological processes with small costs raspisivaem liquid.

In Fig.1 shows a General view of the nozzle, a longitudinal section; Fig.2 is a top view.

The nozzle includes a housing 1, a sleeve 2 and 3, coaxially installed with a gap between itself and the casing 1 and forming a lane is Olsen in the form of an annular series of narrow slits 6, connected to the peripheral channel 4 to feed the atomizer. The outlet slot 7 slots placed on the end of the conical surface 8 of the housing 1. Forming 9 this surfaces 8 intersects the axis of the nozzle at an angle 40oat point a at or beyond the outlet slice nozzle apparatus. The inner channel 5 for the fuel supply is connected through the bypass slit 10 with an opening 11 for supplying liquid fuel and ends the annular outlet nozzle 12, oriented from the axis of the nozzle. On the side of the nozzle at the back made a hole 13 for supplying nozzle in the peripheral channel 4.

The nozzle operates as follows. In the opening 13 serves under the pressure of steam or air through the channel 4 enters the annular slot number of the slots 6, the split railtel stream flowing from the outlet openings 7, placed on the end of the conical surface 8 of the housing 1. Liquid fuel flowing in the channel 5 through the opening 11 and the bypass slit 10, reaches the output of the ring nozzle 12 and runs from him in the form of a thin film. At the outlet from the annular outlet nozzle 12 of the fuel film in contact with jets of spray, broken down into small droplets evenly around the perimeter peripetie torch from the axis of the nozzle in free space.

This design of the nozzle provides quality atomization of fuel, reduces the flow of the spray agent and can find application in many industries where there is a problem of quality atomization of low fluid flow rates.

FIELD: burners.

SUBSTANCE: burner is made of well of specified length (up to 650 mm). The fuel flowing through stabilizer of fuel supply enters the fuel supply pipe and then through fuel nozzles to the mixing chamber of the nozzle.

The compressed steam enters the ring passage defined by the fuel and steam supply pipes. The steam then enters the first (hydraulic) spraing stage of the mixing chamber through the steam nozzles drilled in the swirler radially and tangentially. The mixing chamber is interposed between the hydraulic deflector and exit section of the fuel nozzle. The steam entrains the fuel jet broken down with the deflector and then continues to break it in the second (gas) spraying stage, in the zone around the rod of the hydraulic deflector.
