Known burner for burning fuel oil, comprising a housing made in the form of a snail, with an interior shaft made with the possibility of rotation, which is fixed to the blades of the fan, and fixed to the body axial suction and exhaust pipes for air inlet, nozzle and nozzle placed in a conical glass, rigidly fixed on the shaft, and the actuator (the book "the Rational use of fuel oil in the boilers of the food industry". - M , Light and food industries, 1981, S. 24-27).

The disadvantage of this burner is a low performance due to the lack of supplied air (not more than 10 percent of requirements). To compensate for the lack of air necessary to create a special device for feeding it into the flame of the burner, and this greatly complicates the design of burners and narrows their application in industry, construction and utilities.

Known burner for burning liquid fuel, comprising a housing made in the form of a snail, placed inside the hollow shaft, and the shaft is mounted for rotation, fan, intake and exhaust pipes, ing the tapered glass rigidly mounted on the hollow shaft, the nozzle and the actuator (A. C. the USSR 929964, F 23 D 11/06, from 30.12.77, publ. B 19, 23.05.82 - prototype).

The disadvantage of this burner is its low productivity due to lack of supplied air (not more than 10% of required). Attempts to increase the amount of supplied air lead to complications designs, raising its metal, and hence the intensity. All these shortcomings do not allow to create a unified row of burners with different performance.

The objective of the invention is to improve the performance of the burner, creating a unified row of burners with different performance.

The problem is solved by the burner for burning liquid fuel, comprising a housing made in the form of a snail, placed inside the hollow shaft, and the shaft is mounted for rotation, fan, suction and exhaust pipes attached to the housing, the injector is made in the form of a rod with axial and radial holes, installed the tapered Cup rigidly mounted on the hollow shaft, the nozzle and the actuator, in which according to the invention on the exhaust pipe has an air manifold in the form of a manifold, through the air collector Pro is a, and on the same disk posted by guide elements which, when bond drives with each other to form a cavity, the blades are separated by a guide disk rigidly mounted on the hollow shaft, with the blades mounted on the guide disk and the suction nozzle is performed on both sides of the body.

A comparative analysis of the proposed solutions to the prototype allowed us to identify features that distinguish the proposed solution to the prototype that meets the criterion of "novelty."

Analysis of the proposed solutions with known revealed no solutions, the symptoms of which coincide with the characteristics of the proposed solution that meets the criterion of "inventive step".

The invention is illustrated by drawings, where Fig.1 shows a General view of the burner; Fig.2 - the design of the blades; Fig.3 - the air manifold. Burner for burning liquid fuel consists of a housing 1, made in the form of a snail, placed inside the hollow shaft 2, the shaft 2 is mounted for rotation on the shaft 2 is fixed fan (not shown) with vanes 3, made of two disks 4 and 5 are fastened together, for example, screws (not shown), the disk 4 is made guiding elements 6 made in view of the and the housing 1 is fixed suction 7 and 8 exhaust pipes, in this case the suction pipe 7 is made on both sides of the body. The nozzle 9 is made in the form of a rod 10 11 axial and radial 12 holes. In addition, the nozzle 9 is installed in the cone glass 13. The nozzle 9 and the tapered glass 13 is fixed on the hollow shaft 2 is rigidly, for example, with a thread (not shown).

Axial exhaust pipe 8 is fixed to the nozzle 14, for example, using screws (not shown). On the body 1 of the burner for burning liquid fuel, for example, with screws fixed to the actuator 15, for example, a motor. Exhaust pipe (pipes) 8, for example, with a thread connected to the air manifold 16, made in the form of a header. Through the air collector 16 passes the hollow shaft 2.

In the housing 1 on the hollow shaft 2 is fixed to the guide disk 17, for example, using screws (not shown).

On guide disk 17 is fixed (for example, using screws (not shown), at least two vanes 3. Blade 3 is fixed on both sides of the guide disk and the suction nozzle 7 is made on both sides of the housing 1.

Burner for burning liquid fuel works as follows.

Enables the actuator 15, which causes the rotation of the hollow shaft 2, accommodated in the housing 1, made in the form ulidia blades 3, made of two disks 4 and 5 are fastened together, the disk 4 is made guiding elements 6 which, when bond drives 4 and 5 form the cavity. During the rotation of the blades 3 they the cavity trap air and drop it in the space formed by the exhaust pipe 8, through which (and there may be 1, 2, 3, 4 or more), it enters the air manifold 16, made in the form of a header, in which it accelerates its movement by compressing and accelerating emitted into the nozzle 14. As well as at the end of the air manifold 16 (in the direction of air movement) performed guiding elements (not shown), they give a moving stream of air rotary motion. Due to the fact that the suction nozzle 7 is placed on both sides of the housing 1, the air is supplied simultaneously to the blades 3 with two sides, which significantly increases the amount of air supplied to the burner nozzle 14.

In addition, the presence of the air manifold 16, in which air is not only collected, but also accelerates its movement, allows for the ejection (with certain devices, optional) to increase the air flow to the burner nozzle 14.

At the same time on the hollow shaft 2 is fed under the pressure of the fuel (for example, crude oil is moved radial holes 12 on the conical surface of the glass 13. As the cone glass of 13 from the nozzle 9 is fixed on the hollow shaft 2 is rigidly, the glass 13 from the nozzle 9, revolving, whirling fuel that rotating jet is supplied to the nozzle 14, where, in contact with a rotating jet of air is well mixed. Perenesena fuel-air mixture is ignited with a torch (igniting svedok) and the burner starts to work.

When finished, the actuator 15 is switched off, the fuel supply stop, the burner stops working.

This embodiment of the burner allows you to improve the performance of it to create a unified row of burners with different performance.
