Description

The invention relates to energy and can be used in devices for thermal effects on oil reservoirs.

The aim of the invention is to intensify the combustion process and increase the combustion completeness.

The drawing shows a burner device, a longitudinal section.

The device comprises a housing 1 with a combustion chamber 3 installed therein with an annular gap 2 for passing a cooling agent 3, having a fuel output unit 4 at the inlet and connected downstream to the mixer 5. The combustion chamber 3 is made of head and tail parts 6 and 7, respectively installed with an adjustable end gap 8, while at the entrance of the tail part 7 a mechanical clamp 9 is installed, and its output section is made in the form of a confused nozzle 10. In the case 1 there is a movable insert 11 forming a narrowing conical nozzle 19 sky channel 12 connected to the annular gap 2 for the passage of coolant. The insert 11 is provided with an epiploon 13. A clamping nut 14 is screwed into the housing 1.

The device is also equipped with an igniter 15 and nozzles 16 and 17 for supplying water and air, respectively.

The device works as follows.

Air is supplied to the combustion chamber 3 through the pipe 17 and the swirl. The fuel is atomized by the nozzle and, interacting with the swirling air flow coming out of the swirler, forms an air-fuel mixture, which is ignited by the igniter 15. The cooling water passes through the nozzle 16 into the gap 2 of the 3 combustion chambers and cools the wall injections

It goes into the mixer 5, where, mixing with the combustion products, it forms a vapor-gas mixture. A portion of water (2-3% of the bulk) is injected through the end gap 8 into the inside of the combustion chamber. Pinch 9 ensures the removal of products of incomplete combustion from the wall zone to the core of the flow, intensifies the combustion process, and improves the displacement of the combustion products with water injected through the gap 8. Water flow through the gap 8 is controlled by changing its width by pushing or loosening the nut 14. moving the tail 7 up at. tightening the nut 14 and down while loosening during the operation of chamber 3 of combustion from the pressure in the chamber. The gland 13 prevents leakage of water from the annular space between the housing 1 and the combustion chamber 3 ..
