Description

The invention relates to energy, can be used in industrial steam generators, as well as in furnaces and other heat installations, and is an improvement of the invention according to the author. No. 1339349.

The purpose of the invention is to increase efficiency by providing air heating.

Figure 1 schematically shows the proposed burner device, rhodonal section; in figure 2. - section aa in figure 1; on fig.Z - section bb in figure 2.

The burner unit contains coaxially arranged central fuel delivery unit 1, air supply duct 2 and peripheral flue gas duct 3, additional device 4, made in the form of an axial fan with blades in air duct 2 and peripheral duct 3. Device at the entrance to the air feed channel 2, there is an iris gate 5. The fuel delivery unit 1 has a spring-loaded plunger 6, kinematically connected with the actuator 7 of the iris valve 5. The fuel delivery unit 1 is additionally equipped with a sylphon 8, one end It is connected to the housing 9 of the assembly 1, and the other to the lane, a forged glass 10 rigidly fastened to the plunger 6 installed in the pipe 11 with slit-shaped slots 12 for the passage of gas. Stock

13 displacement force from the gas pressure is installed in the peripheral flue gas channel 3 between the housing

14 devices and the ends of the blades of the first axial fan. On the shaft 15 of the engine 16 between the iris shutter 5 and the engine 16 are installed additional blades 17 of the second axial fan. The first axial-flow fan is equipped with inlet guides and output springs ml 18

and 19, respectively, made of common sheet blades installed in channels 2 and 3. The device is also equipped with a cylindrical gate 20 with a displacement handle 21, a gas collector 22 and a gate 23. The fuel delivery unit 1 is connected to a gas collector 22 t by the Rub 24, and the plunger 6 through the ferrule 25 is bonded to the rod 13. The device is also equipped with inlet and outlet nozzles 26 and 27 for supplying flue gases and

neck 28 installed in the wall 29 of the combustion chamber. The fuel discharge unit 1 is equipped with gaztuskny holes 30 for gas supply to the neck 28..

The burner device operates as follows.

Flue gases are supplied to channel 3 and air to channel 2. As a result of heating the upper part of the hollow blades of the blade apparatus 4, the coolant evaporates in them and moves to the air movement zone through channel 2. The atmospheric air heats up, and the coolant vapor condenses, centrifugal force is moved again to the upper part of the hollow blades of the apparatus 4, made in the form of heat pipes. Then, the preheated air, swirling with the first fan, is fed into the neck 28 through the spraying apparatus 19, and the flue gases, cooling and. The passage through the tops of the lower part of the apparatus 19, moving through the channel 3 and thrown into the outlet port 27. Part of the flue gases can be discharged through the neck 28 into the furnace. The gas through the manifold 22, pipe 24 is supplied to the inside of the assembly 1 between its body 9 and the bellows 8 and then passes under the cup 10. When the gas flow rate increases, the pressure on the bellows 8 and the latter increases is compressed, simultaneously moving the cup 10 to the right. The plunger 6 is rigidly attached, it also moves to the right and opens slots 12 inserted in the pipe 11.

The gas then passes holes .30 and is fed into a swirling flow, where it ignites and forms a flare. When moving the plunger 6 one way to the right, temporarily the valve 25 and the rod 13 move to the right, moving the actuator 7 of the iris shutter 5, which increases the flow of atmospheric air supplied to the combustion. When gas consumption decreases, the process of adjusting the gas-air ratio occurs in the opposite direction. In order to increase the efficiency of the burner operation, the first fan is equipped with an inlet guide device 18 and an output distributor device 19 made of common sheet blades. This allows an increase in heat transfer from the flue channel 3.

on channel 2, on the one hand, and on the other, to increase the pressure created by the fan, i.e. to increase the reliability of the burner operation when the vacuum pulsations in the furnace. For the same purpose, the blades 17 of the second axle are used, which contributes to cooling the engine casing 16. By selecting the required number of slots 12, their configuration, as well as the rigidity of the bellows 8, the gas-air ratio can be proportioned. The use of the bellows 8 also increases the reliability of the operation of the device due to the elimination of gas leaks in addition to the exhaust rejections 30.
