Description

The invention relates to lighting, in particular, to flames with an open flame, and can be used in mass events as a decorative means for carrying fire.

The aim of the invention is to provide combustion with a given flame height with stable parameters of decorative flame color, regardless of meteorological conditions and the position of the flame in space.

FIG. 1 shows a torch, a longitudinal section; in fig. 2 — node I in FIG. one; in fig. 3 - the node L in FIG. one; in fig. 4 — node III in FIG. one.

The torch includes a housing 1 and a handle-tank 2 for fuel, connected to the housing 1 by a threaded connection 3. In the handle-tank 2 there is a valve of push action 4 with a sealed element 5 on the valve stem. A split spring ring 6 is located between the housing 20 and the handle 2 of the tank 2. The trunk 7 connecting the handle tank to the metering device 8 has a check valve 9 in the lower part, and in the upper hour g seals the valve stem 4 from the cavity between the casing and the handle-reservoir 2. The liquefied gas enters the line 7, the check valve 9 passes, the conical cavity 10, where the gas starts to be heated due to the heat supply through the wall from the adjacent conical cavity 22, and the filter 1 and through the metering device 3 enters in ne egrevatelnuyu chamber 16, wherein the phase forming process is steam gas fuel mixture. The ribs 17 are constantly located in the zone.

This conical cavity 10 and the filter 11. Dozi-flame, stabilize the thermal state

fuel overheating chambers. The location of the cutout 20 of the tube 19 in the upper part of the overheating chamber does not allow the liquid gas phase to penetrate to the ejector 13 and the nozzle 23

The steering device 3 consists of a rotary throttle needle 12 enclosed in the housing 13. A cap 14 is located above the metering device 3, closing the control hatch 15. The superheater chamber 16., the ejector. Gas vapor, passage through tube 19,

equipped with ribs 17 and connected to the ejector 18 via a tube 19, the upper edge of which 20 is removed from the bottom 21 of the superheater chamber 16, and the lower edge enters the conical volume 22, from the lower part of which the nozzle 23 of the ejector comes out. The aperture 24 of the ejector-13 is directed along the axis of the POKT of the coloring device 25. In the lower part of the ejector there are air intake windows 26 connected to the atmosphere of the cavity 27 and windows 28. The coloring device 25 is designed as a sliding cylinder 29. 40 filled bulk solids such as strontium or sodium. The lower part of the cylinder 29 is made mesh in the direction of the inner cavity 30 of the burner. The upper part of the tamping device 31 has a series of flat holes 32, the exit is 1 cx to the burning zone 33. In the middle part of the tinting device, there is a sealing rubber ring 34. The inner cavity 30 of the burner is associated with the burning zone of 33 ko. Five grooves 35. Around the burner 50 is an annular outer casing 36 having a series of longitudinal slits 37.

The torch works as follows.

Preliminarily, depending on the ambient air temperature, the dosing device 8 is adjusted by turning the throttling needle 55 relative to the housing 13 through the hatch 5 with the plug removed 14. The angle of rotation is determined in advance from the temperature

The vapors of the mixture enter the ejector nozzle 23, accelerate and draw air from the atmosphere through the windows 28, the cavity 27 and the windows 26. At the mouth of the ejector 24, the gas-air mixture flows into the internal cavity 30 of the burner. The main volume of the gas-air mixture through the annular gap 35, which is formed by the outer casing 36, passes into the zone 1 of Territory 33. A smaller part of the gas-air mixture penetrates through the mesh bottom extension) {O10 cyl (1dr 29, carries loose salt particles through a number of calibrated holes 32, located in the upper part 31 of the covering device 25. Salt particles enter the combustion zone by stably and intensively tinting the flames. The extension of the cylinder 29 changes both the air supply of the coloring matter and the distance to the mouth of the 24 ejector, which controls the intensity the flame tinting and the life of the tinting device. When the torch is turned on, the handle-tank 2 is turned to the size of the split ring 6. At the same time, the check valve 9 is activated, preventing liquid

according to the results of experimental work. Then, the handle-tank 2 is screwed into the torch along the thread 3 up to the stop in the removable ring 6, which prevents the torch from switching on automatically. Finally, a tinting device 25 is inserted into the upper burner housing. At the same time, it is fixed in the housing with a rubber sealing ring 34. The flame prepared in this way is ready for operation. To ignite the flame split

0, the removable ring 6 is removed from the torch. The handle-reservoir 2 along the thread 3 is turned into the housing, thereby ensuring the opening of the valve 4 of the pressure action and the check valve 9. The sealing ring 5 at the same time

g seals valve stem 4 from the cavity between the housing and the handle-reservoir 2. The liquefied gas enters the line 7, passes the check valve 9, the conical cavity 10, where the gas starts to be heated due to the heat supplied through the wall from the adjacent conical cavity 22, and the filter 1 and through the metering device 3 enters the superheating chamber 16, where the vapor phase of the gas fuel mixture is formed. The ribs 17 are constantly located in the zone.
