The known device is a burner and has a glass-like body with a figured lid, a flat bottom, a flat oxygen distributor, a flat hydrogen distributor. Tubes for hydrogen and oxygen are mounted in the distributors, forming the nozzle of the burner. The nozzle centers are located at the intersection of the system of equidistant parallel lines, intersected at an angle of 60 ° C with the same system of lines, and also has a space between the bottom of the burner and the hydrogen distributor for water.

The design of the known device does not allow you to organize a controlled process of burning hydrogen, which significantly affects the manufacturability of the process from the point of view of safe operation of this burner and does not provide a reliable ignition process.

The objective of the proposed technical solution is to increase the reliability and safety of the start-up and operation of the device.

The problem is solved by a device for burning hydrogen, including a cylindrical body with three lines for supplying oxygen, hydrogen and water, a cover, a bottom, oxygen and hydrogen distributors, in the lower plane of which tubes are mounted, respectively, oxygen tubes and hydrogen tubes that form the nozzles, and also containing between the bottom and the hydrogen distributor a space for water, namely its feature, which consists in the fact that the device additionally includes two burners mounted in the lid full-time devices and a central tube with a flame control device, while the burner devices, identical in design, have oxygen and hydrogen inlets, a gas mixture channel and an ignition device integrated in the channel, while the channels of the burner devices communicate with the central tube, in addition, in the bottom there are holes for water outlet in the form of nozzles coaxially located to the nozzles.

Figure 1 (side view) and Figure 2 (top view) schematically shows the design of the device.

Declared as a utility model, the device consists of a cylindrical body (1) with three lines for supplying fuel (hydrogen - 2), an oxidizing agent (oxygen - 3) and water - 4, which serves to cool the inner surface of the bottom and reduce the temperature of the flame (flame) - hereinafter referred to as "balancing water", includes the appropriate resource allocators: 5 - hydrogen; 6 - oxygen, 7 - ballast water. In this case, the lower parts of the distributors form distributing planes, respectively, of hydrogen - 8, oxygen - 9, ballast water - 10. The device includes a cover - 11, a bottom - 12. Two burner devices (13) and (14) and a central tube are mounted in the cover (15), equipped with a flame control device with a photocell - 16. Burner devices are identical in design and incorporate oxygen supply - 17, and hydrogen - 18, a gas mixture channel - 19, and an ignition device built into the channel - 20. Burner devices (pilot burners) dissolved function and produce the initial ignition flame. The channels of the pilot burner are connected (communicated) with the central tube and the flame from the pilot burner enters the central tube - 15.

The central tube is an optical channel for the photocell sensor of the flame control device - 16, and the presence of two pilot burners (13 and 14) operating simultaneously provides reliable ignition and inclusion in the operation of the device.

The interconnected elements - the pilot burner, the central tube with the flame control device - form the ignition system of the inventive device.

The dispensing planes of the resource distributors (hydrogen and oxygen) have tubes, respectively, oxygen tubes — 21, hydrogen tubes — 22, and the bottom plane 12, which coincides with the dispensing plane of the ballast water 10, has water outlet openings made in the form of nozzles 23, while the oxygen, hydrogen, and water outlet nozzles are coaxially located relative to each other and form trembling coaxial-jet nozzles in the bottom plane, which makes it possible to optimally cool the outer walls of the oxygen tubes (21) and the inner erhnost bottom (12). The nozzles are evenly distributed on the bottom plane around the central tube. The number of nozzles in the plane of the bottom is determined by the given performance of the device for burning hydrogen. The mixture of gases (hydrogen and oxygen) and combustion takes place in the plane of the bottom at the cut of two-component nozzles. Ballast water is used not only to cool the structural elements of the device, but to control the temperature of the flame.

The design of the device and the sequence of actions for ignition and operation of the burner, due to the design features, ensure reliable start-up of the device and its safe operation.

A device for burning hydrogen works as follows.

Before commissioning, the device for burning hydrogen is purged with nitrogen. Oxygen and hydrogen are supplied to the pilot burners, with a stable and predetermined fuel and oxidizer flow rate, they include an ignition device. The flame control device generates a flame signal in the central tube. Open the supply of oxygen, hydrogen and ballast water in the respective valves. The gas mixture begins to burn. The presence of a flame in the central tube confirms the inclusion of the device in operation. Turn off the ignition device. Close the oxygen supply to the pilot burner. After turning off the ignition device, only hydrogen is fed into the central tube. The start and operation of the device is carried out automatically using a system of automatic devices, sensors and regulators, which are not structural elements of the claimed device.
