Burner for burning liquid fuel

 

The invention relates to burners for burning liquid fuel. Burner for burning liquid fuel includes a housing made in the form of a snail attached to the housing axial suction and exhaust pipes for air supply, placed inside the hollow shaft for supplying fuel to the injector, while the shaft is made to rotate, which is fixed to the blades of the fan, nozzle, placed in a conical beaker, and the nozzle and a conical Cup rigidly mounted on the hollow shaft, the actuator and the nozzle in the axial exhaust tube is solid horizontal partition wall for dividing the air flow, while the front end (in the direction of air movement) partitions are made with adjustable air flow, in addition, axial exhaust tube is mounted for movement along the centerline of the burner and between the burner housing and the axial exhaust pipe has a slit for the ejection of air. The invention allows to increase the efficiency of the burner due to the more complete combustion of fuel with the airflow and increase its performance. 1 Il.

The invention includes in burners for the construction, agriculture and the food industry.

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 drive. (The book "the Rational use of fuel oil in the boilers of the food industry". Light and food industries. M., 1981, S. 24-27).

The disadvantage of this burner is low efficiency due to underburning of fuel oil, the impossibility of adjusting the flow of fuel for combustion due to the lack of incoming combustion air.

Famous oil-gas burners, comprising a housing made in the form of a snail, fan motor, korotkovremennouu injector, mixer, fuel line, made in the hollow shaft (Book "Steam and hot water boilers", Energoizdat. M., 1987, S. 76-81 prototype).

The disadvantage of this burner is low performance, incomplete combustion, the impossibility of increasing the number of burn the efficiency at the expense of combustion efficiency, the increase in the quantity of fuel combusted by increasing the air supply of the burner in the furnace, increasing its productivity.

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 supplying fuel to the injector, while 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 supply, injector, placed in a conical glass rigidly mounted on the hollow shaft, the actuator and the nozzle according to the invention in axial exhaust tube is solid horizontal partition wall for dividing the air flow, while the front end (in the direction of air movement) partitions are made with adjustable air flow, in addition, axial exhaust tube is mounted for movement along the centerline of the burner and between the burner housing and the axial exhaust pipe has a slit for the ejection of air.

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 is akami proposed solutions that meets the criterion of "Inventive step".

The invention is illustrated a schematic diagram, which shows a General view of the burner.

Burner for burning liquid fuel includes a housing 1, made in the form of a snail, inside the housing 1 is placed a hollow shaft 2 made with the possibility of rotation on the hollow shaft 2 fixed blades of the fan 3 (for example, using screws, not shown). On the housing 1 is fixed suction pipe 4 and the axial exhaust pipe 5 for supplying air. On the shaft 2 is fixed to the nozzle 6, is placed in a conical glass 7.

The nozzle 6 and the tapered glass 7 mounted on the hollow shaft 2 is rigidly. On the housing 1 is fixed to the actuator 8, and the exhaust pipe 5 is fixed to the nozzle 9.

In the axial exhaust pipe 5 made a solid horizontal partition 10 (e.g., sheet metal) for dividing the air stream into two streams: internal and external.

Internal flow with high pressure on a narrow section with the guide elements (not shown), which divides the fuel bar (stream) coming out of the glass 7.

External flow passing through the free cross-section between the partition 10 and the nozzle 9 (made, for example, in the form of a Laval nozzle), allows to enrich the zdwhu the question of fuel atomization and the maximum saturation of the mixture with air, eliminates the surging and optimized energy consumption of the fan 3.

The exhaust pipe 5 is mounted for movement along the axis of the housing 1, for example, by means of the rack and the gear wheel (shown). It is necessary to create an additional stream of air created by ejection through the slit II between the axis of the exhaust pipe 5 and the housing 1. Gap II by moving the axial exhaust pipe 5 can be increased by increasing the flow of air, or may overlap due to the tight fit of the axial exhaust pipe 5 to the housing 1, stopping further flow of air.

The burner works as follows.

Before burning the suction nozzle 4 is closed, axial exhaust pipe 5 are pressed against the housing 1, the front end of the partition 10 is pressed against the housing 1. Enables the actuator 8, the fuel on the hollow shaft 2 is supplied to the injector 6. The nozzle 6 raspisyvaet fuel in a conical glass 7, which feeds its rotating film in the nozzle 9. Fuel, for example, the torch is ignited, it starts burning. As the warm burner opens the suction nozzle 4, which is the air pumped by the blades 3 through the axial exhaust pipe 5, which is made of napravlyayusya fuel the front end of the partition 10 is installed in the housing so as to ensure efficient combustion. With further increase of fuel flow axial exhaust tube using, for example, Reiki with the toothed wheel (not shown) is discharged from the housing 1. Forms a slot through which begins the ejection of air. Thus is governed by the efficiency of the burner and the combustion efficiency.

At the termination of the operation of the burner fuel supply cut off, the axial exhaust conduit 8 by means of, for example, slats, gear, move in tight to the body 1, closing the gap, the front end of the partition 10 are pressed to the housing 1, the suction nozzle 4 is closed, the actuator 8 is turned off. The burner is disabled.

The proposed invention allows to increase the efficiency of the burner due to the more complete combustion of the fuel, increasing air flow and increase its performance.
