Description

 The invention relates to energy and can be used to obtain a coolant.

 A steam-water plasmatron is known, comprising a housing, an electric holder mounted therein with an electrode fixed therein, a nozzle mounted on the housing with a gap relative to the electrode forming an arc-forming chamber, a branch pipe system in the housing, a water supply pipe with a regulating device, and a steam generation device ( patent N 2041039 IPC 23 K 10/00).

 There is a known method of plasma cutting of metal, in which a water-containing medium is used, supplied by two streams, one of which, a worker, serves for plasma formation, and the other, additional - to protect the cutting arc (patent N 2060128 IPC 23 K 10/00).

 However, the steam-water plasmatron and the method of plasma cutting of metal have limited technical capabilities (cutting, welding, surfacing) and cannot be used to obtain a coolant.

 A known method of producing a heated working medium by mixing fuel with an oxidizing agent and then burning the resulting mixture on a catalyst in a combustion chamber (patent N 1327796 IPC F 23 C 11/00 - prototype).

 However, this method has a complex technological scheme (fuel is pre-mixed with water at a mass ratio that provides thermal self-enrichment of the fuel, and the oxidizing agent is fed into the mixture in a stoichiometric amount when the heated working medium is obtained in the process of combustion as a mixture of evaporated water and combustion products) and limited the possibilities associated with the stationary execution of the device, a special selection of fuel and high energy consumption for preheating the fuel mixture, and t It also does not have ease of maintenance and does not ensure the environmental safety of the process of obtaining a heated working environment.

 The invention is aimed at simplifying the technological scheme of the process of obtaining a coolant, expanding its technical capabilities and applications, ensuring environmental safety and ease of maintenance.

 This is achieved by the fact that a plasma torch is formed in the combustion chamber by using an electric current, magnetic field and water or aqueous solutions, and during the combustion process a heat carrier is obtained in the form of superheated steam and combustion products, which are sent by pipelines and adjustable elements to ensure the operation of the devices for heating water, cooking and heating the room.

 The invention is illustrated in the drawing, which shows a structural diagram of an implementation of the method of using plasma to obtain a coolant. The drawing shows the following notation: 1 - capacity for water or aqueous solutions; 2 - plasmatron; 3 - a combustion chamber of a plasma torch; 4 - pipeline for supplying coolant for space heating; 5 - valve (adjustable element); 6 - pipeline to ensure the operation of the device for cooking; 7 - pipeline for heating water; 8 - pipeline for returning the spent coolant; 9 - pipeline for supplying water or aqueous solutions to the tank 1.

 The method is as follows.

 When applying voltage to the plasma torch 2 and turning it on, a spark arises, which develops into an arc discharge. When water or aqueous solutions are supplied to the arc discharge zone and due to strong heating, steam is formed. As a result of the high temperature of the arc discharge and the vapor pressure, the plasma is pushed through the axial hole into the combustion chamber 3, where a plasma torch is formed. In the combustion chamber, steam overheats. Superheated steam and combustion products form a coolant, which through pipelines (4,6,7) and adjustable elements 5 enters the devices for heating the premises, cooking and heating water. As necessary, this or that pipeline can be blocked using the appropriate adjustable elements 5.

 The coolant (superheated steam) moves through the pipelines and performs its main function - it gives off heat. After that, he can heat the water in the tank 1 or turn into water, which is reused in a closed cycle.

 The use of this method can significantly simplify the process of obtaining a coolant and heat transfer, expand its capabilities and applications, ensure environmental safety and ease of maintenance.
