Will invent relates to burners for burning liquid fuel and can be used in utilities for heating water in boilers, as well as in construction, agriculture and the food industry.

Known burner for burning fuel oil, comprising a housing made in the form of snails placed inside the shaft is made to rotate, 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. Light and food industry". M., 1981, p.24-27).

The disadvantage of this burner is the inability to burning different kinds of liquid fuel, which limits the use of burners, as well as low productivity and low efficiency.

Known burner for burning liquid fuel, comprising a housing made in the form of snails placed inside the hollow shaft for the fuel pump, and the shaft is mounted for rotation with a fixed fan blades, axial suction and exhaust pipes for air supply attached to the housing, a nozzle mounted in the tapered glass is, moreover, the nozzle and cone Cup rigidly mounted on the hollow shaft, the nozzle and the actuator (A.S. USSR №929964, F 23 D 11/06, from 30.12.77, publ. BI # 19 of 23.05.82 - prototype).

The disadvantage of this burner is that it is impossible combustion of various fuels, low burner capacity and low efficiency.

Object of the invention is the expansion of the combusted fuel, and improve the performance of the burner and increase efficiency.

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 for the fuel pump, and the shaft is mounted for rotation with a fixed fan blades, axial suction and exhaust pipes for air supply attached to the housing, a nozzle mounted in a conical beaker, and the nozzle and a conical Cup rigidly mounted on the hollow shaft, the nozzle and the actuator according to the invention, the actuator is fixed to the body in the suction pipe between the walls of the socket and the housing has a gap for the passage of air, and the drive shaft is made hollow for the passage of fuel to the nozzle, while the drive shaft is placed coaxially with the hollow shaft of the burner and connected with it.

The burner according to the invention is made so that the on shaft of the actuator is fixed emulsifier to obtain an emulsion or suspension and fuel supply and (or) water emulsion.

The burner according to the invention is performed so that the drive shaft is fixed a valve for fuel.

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

Comparative 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 in the drawing, which shows a General view of the burner.

Burner for burning liquid fuel consists of a housing 1, made in the shape of a snail. In case 1 posted by hollow shaft 2 fuel. The hollow shaft 2 is mounted for rotation. On the hollow shaft 2 fixed blades 3 fan. On the housing 1 is fixed intake 4 and exhaust 5 connections for air supply. The nozzle 6 is installed in the cone glass 7. The nozzle 6 and the tapered glass 7 is rigidly mounted on the hollow shaft 2. The burner also includes a nozzle 8 and the actuator 9. The actuator 9 is fixed on the housing 1 in the suction pipe 4. Between the housing 9 and the walls of the inlet tube 4 there is a gap of 10 for the passage of air to the blades 3 of the fan.

The drive shaft 9 is made hollow (not shown)placed coaxially with the hollow shaft 2 of the burner and connected with it, for example, using the screw is soedineniya or cotters, or with polyurethane bushings. In addition, the drive shaft 9 can be attached emulsifier 11 to create, for example, water-oil, water-oil emulsion to increase the performance of the burner and increase efficiency. During long-term storage of crude oil splits into water and oil, the same happens delamination waste oil. Combustion of these mixtures is uneven combustion 4, this decreases the performance and efficiency of the burner.

The use of the emulsifier allows to obtain a homogeneous emulsion, which greatly increases the efficiency of the burner.

In addition, the use of the emulsifier allows you to burn water-coal slurry, or suspension of oil and waste oil with coal dust, etc.

On the drive shaft 9 is mounted a valve 12 (e.g., in the form of a tee) for supply of various fuel types to the nozzle 6.

For example, the ignition of the burner is carried out at the flow to the nozzle 6, diesel, and after a warm-up burner valve with a fuel block and open the faucet with crude oil, etc.

The burner operates as follows: switch on the actuator 9, which transmits the rotation of the hollow shaft 2 with fixed blades 3 fan. The blades of the fan 3 to deliver air from a suction pipe 4 to you is lopomo the pipe 5. As well as in the exhaust pipe 5 is made guiding elements (not shown), the turbulence of the air flow, which with high speed escapes out of the exhaust pipe 5. Open the valve 12 and is fed, for example, diesel oil, which is on the hollow shaft 9 and the hollow shaft of the burner 2 is supplied to the injector 6, which raspisyvaet fuel on a rotating glass 7.

Rotating jet fuel in the nozzle 8 is found with rotating air stream and well sprayed. Sprayed fuel is ignited, for example, a flame (candle) and the burner starts to operate. Thus the air flowing in the suction pipe 4, is heated from the actuator (actuator) 9, and the fuel, passing through the hollow shaft 9, is heated from the working drive that promotes quality and complete combustion of any liquid fuel, including emulsions and suspensions. After a warm-up burner and the operating condition of the valve 12 with the diesel fuel covered and opens the valve 12 with a slurry of water with coal dust, which is served in the emulsifier 11, in which is obtained a water-coal suspension supplied then on the hollow shaft 9 and the hollow shaft 2 of the burner nozzle 6, and burned. When burning a mixture of diesel fuel with coal dust is fed pulp diesel fuel with coal dust in the emulsifier 11 and in the form of suspension is burned.

When burning crude is Efti, fuel oil or waste oil requires constant heating them that is in the hollow shaft of the actuator 9 from the heating actuator, which greatly facilitates the operation of the burner, increases performance and efficiency.
