A device for szhizrani fuel, containing burners mounted on opposite sides; na flue space

The disadvantage of the device is disordered fuel combustion.

Closest to that proposed by technical means is a device for burning fuel, containing a combustion chamber, installed 6 (tEie is flush with one another and the exhaust ducts, and allows the furnace to form a flue process due to the collision of jets of a fire mixture 2.

The disadvantage of the device is a low ignition intensification due to fan-like spreading of the colliding jets.

The object of the proposed device is to intensify the combustion by more fully using the oncoming movement of the mountains. flows.

The goal is achieved by the fact that the combustion chamber is made in the form of an axisymmetric tunnel with openings.

The ends are located between the gas discharge channel channels, and its length is the diameter, and the area of the flow section is 3-10 of the area 5 of the flow diameter of the burner.

The drawing shows a schematic longitudinal section of the device.

The inquire contains the same to coaxially set up one against the fugue burner 1 and the combustion burner, the range of which is connected to the fS gdeo (1 tunnel 2), the range of which is connected to the fS gdeo (the range of the output for the output of the circuit is six. The effect of correlating the length of the tunnel 2 to the diameter should be within 4-5, and its passage area 20 sections 3-10 times the area of the flow area burner 1.

The fuels) sound streams emanating from burners 1, ignite from 25 exhaust gases to the canals - 3 collide in the middle of tunnel 2, each turn in the opposite direction and end tunnel 2 at high speeds, increasing the level of turbulence and intensity. heat and mass transfer in the mixing and burning zone.

The application of the proposed device is most effective when burning heavy liquid fuels (fuel oil, tar, sulfur, etc.). When introducing unburned Drops of t.op. willow into a counter-flow of products, the groupings lead to their addition crushing and crushing.
