Description

The technical field to which the utility model relates.

The utility model relates to a power system and can be used as a generator of thermal energy to generate electric current.

State of the art

Known emulsion nozzle for burning fuel, comprising a housing, a Laval nozzle, to the end of which a spray is supplied, and radial holes are made in the diffuser section. In addition, a pipe is installed along the axis of the housing, and a reflector is formed at the outlet, which forms a gap with the end of the housing. In the central part of the reflector there is a through channel connected to the pipe and equipped with a swirler made in the form of tangential channels or a screw insert (Auth. St. USSR No. 960494, M. class. F23D 11/16, published September 23, 1982, Bull. No. 35 )

Signs that are common to the known and claimed technical solutions are the presence of a Laval nozzle.

The reason that prevents obtaining the required technical result in a known technical solution is that the atomizer is fed into the Laval nozzle, and the liquid fuel is introduced into the atomizer stream, where liquid oil is atomized due to the supersonic atomizer stream and also due to the shock wave of the shock waves. .

The closest analogue (prototype) is a device for burning fuel, containing a housing with a Laval nozzle located in it, connected to an input to a spray source, inside the housing coaxially with a Laval nozzle there is a pipeline whose inlet is connected to a fuel source through a mixing head, and the output is combined with a critical section of the Laval nozzle, the mixing head being connected to the spray source and provided with nozzles tangentially inclined to the longitudinal axis, configured to supply s pipeline nebulizer, which is used as water vapor (RF Patent №2099636 C1, M. cl. F23D 11/00, published 12.20.1997).

Signs that are common to the known and declared solutions are the presence of a Laval nozzle and means of supplying water vapor to the nozzle.

The reason that prevents obtaining the required technical result in a known technical solution is the use of a Laval nozzle for the formation of a steam-fuel mixture from which only hydrocarbon fuel is burned, and water vapor is used only for spraying this fuel.

Utility Model Essence

The problem the utility model aims to solve is to generate thermal energy without the use of hydrocarbon fuel.

The technical result that mediates the solution of this problem consists in the multi-stage combustion of water fuel (i.e., fuel formed by the separation of water into hydrogen and oxygen), in which water fuel in the next stage is burned using plasma obtained from the combustion of water fuel in the previous stage .

The technical result is achieved in that the device for burning fuel is made in the form of either a linear chain of Laval nozzles, in which the output of the previous nozzle of the circuit is connected to the input of one subsequent nozzle of the chain, so that the geometric dimensions of the subsequent nozzle of the chain exceed the geometric dimensions of the previous nozzle of the chain, or a branched chain Laval nozzles, in which the output of the previous nozzle of the circuit is connected to the inputs of two subsequent nozzles of the circuit, while at the end of the first nozzle of the circuit there is an nozzle for supplying water or drop water to it steam and electrodes to create an electric arc designed to dissociate this water, and each subsequent nozzle of the circuit contains a nozzle for supplying additional water or water vapor into it.

The technical result is also achieved by the fact that the first nozzle of the circuit contains a line for supplying plasma from the output of this nozzle to its input.

The novelty of the claimed technical solution lies in the implementation of the device in the form of a linear or branched chain of Laval nozzles, designed to burn water fuel.

Information confirming the feasibility of implementing a utility model

The device in its embodiment in the form of a linear chain of Laval nozzles (Fig. 1) contains at least two Laval nozzles 1 and 2. Moreover, the input of the second nozzle 2 (its inlet end) is connected to the output of the first nozzle 1. At the inlet (at the inlet end) ) the first nozzle 1 is fitted with a nozzle 3 for supplying water or water vapor, and electrodes 4 (cathode, anode) are installed for connecting them to a high voltage current source. The nozzle 1 also contains a line 5 for supplying plasma from the output of this nozzle to its input. The nozzle 2 contains a nozzle 6 for supplying additional water or water vapor to the region of its critical section. In addition, the geometric dimensions of the nozzle 2 exceed the geometric dimensions of the nozzle 1.

The device in its embodiment in the form of a branched chain of Laval nozzles (figure 2) contains at least three Laval nozzles 1, 2 (1) and 2 (2). In this case, the inputs of the second 2 (1) and third 2 (2) nozzles (their input ends) are connected to the output of the first nozzle 1, which is divided into two output channels using a splitter 7. At the input (at the input end) of the first nozzle 1 the nozzle is set 3 for supplying water or water vapor, as well as electrodes 4 (cathode, anode) are installed for connecting them to a high voltage current source. The nozzle 1 also contains a line 5 for supplying plasma from the output of this nozzle to its input. Nozzles 2 (1) and 2 (2) contain nozzles 6 for supplying additional water or water vapor to the region of their critical sections.

The operation of the device is as follows.

Water or water vapor is supplied to the Laval nozzle 1 by means of a nozzle 3. The electrodes 4 are temporarily connected to a high voltage current source. As a result of the passage of current, water decomposes into hydrogen and oxygen and subsequent combustion of hydrogen with the formation of a primary plasma in nozzle 1, the temperature of which reaches 6000 ° C. A part of this plasma is fed through the line 5 to the inlet of nozzle 1. This reverse plasma takes on the function of splitting water, since a temperature of 3000 ° C is sufficient for this splitting; while the supply of electric current to the electrodes 4 is stopped. The plasma generated in the nozzle 1 enters the next nozzle 2 of the nozzle chain (Fig. 1) or, being divided into two flows by a separator 7 (Fig. 2), simultaneously into the next two nozzles 2 (1) and 2 (2). Additional water (or water vapor) enters this next nozzle (or nozzles) by means of nozzle 6, which, under the influence of the primary plasma, decomposes from the first nozzle into hydrogen and oxygen, while the newly formed hydrogen also burns. As a result, an additional plasma is formed in the second nozzle, increasing the total volume of the generated plasma. Thus, with small dimensions, the device allows the generation of significant thermal power based on water, which can be effectively used in the electric power industry.
