Description

 The invention relates to the field of energy, transport engineering and can be used in heat engines of various types and purposes - boiler furnaces, heat generators, heat engines, etc.

 A known method of catalysis of combustion processes, including catalytic treatment and feeding into the combustion chamber through channels of fuel, an oxidizing agent, mixing and igniting the resulting mixture (see Big Soviet Encyclopedia Dictionary, M., "Soviet Encyclopedia, 1972, p. 80," Combustion").

 This method has a number of disadvantages. Firstly, during combustion, due to the heterogeneity of the fuel mixture with the oxidizing agent, local overheating zones arise, which increase the formation of harmful nitrogen oxides. Secondly, a large amount of fuel is spent on unproductive types of work.

 The problem to which the present invention is directed is to increase the efficiency of the catalysis of combustion processes.

 EFFECT: reduction of fuel consumption and reduction of harmful combustion products due to electromagnetic catalysis of combustion processes.

 The technical result is achieved by the fact that in the method of catalysis of combustion processes, including catalytic treatment, feeding into the combustion chamber through channels of fuel, an oxidizer, mixing and igniting the resulting mixture, the catalytic treatment is carried out by an electromagnetic field, for which modulated signals are fed from the electromagnetic generator to the emitters with carrier frequency from 100 to 2000 kHz, modulation frequency from 1 to 200 kHz and deviation with a frequency of 1 Hz, and emitters generate an electromagnetic field, the electrical component The distance does not exceed 0.02 V / m, and the magnetic one does not exceed 0.00002 A / m.

 Depending on the need, the electromagnetic field is treated with a fuel channel, an oxidizer channel, a combustion chamber or all equipment.

 The processing of a particular node depends on the type of heat engine and the specific tasks to be solved. To work in a stable mode, pre-treatment with an electromagnetic field is carried out before burning, based on the condition 0.06-0.0002 hour / kg.

 The indicated population includes all essential features, each of which is necessary, and all are sufficient to achieve a technical result.

 The implementation of the method is illustrated by the example of a gas turbine engine.

 The emitter is installed on the fuel supply pipe. The electromagnetic generator is turned on and a modulated signal is supplied to the emitter. A signal with a carrier frequency of 100 to 2000 kHz is modulated by a signal with a frequency of 1 to 200 kHz, and the modulated signal is subjected to deviation with a frequency of 1 Hz. The emitter generates a modulated electromagnetic field, the magnetic component of which does not exceed 0.00002 A / m. This field acts on the material of which the pipeline is made, and on fuel. As a result, the properties of both the substance of the pipeline and the fuel change. Depending on the range of selected frequencies, the properties can vary both upward and downward. For maximum process optimization, the emitter is also installed in front of the compressor on the oxidizer (air) supply line.

 Optimization of the combustion process is achieved by changing the properties of fuel and air. The fuel and air supplied to the combustion chamber under the influence of a modulated electromagnetic field change their viscosity properties - internal gas friction, gas friction on the pipe wall or pipeline construction elements (axial compressor vanes, centrifugal process gas blower). As a result of changes in the aggregate viscosity properties of gas and air and their secondary manifestation — diffusion, interdiffusion, the mixture of gas with air becomes more uniform in composition. As a result of this, the number of zones of local overheating is reduced, the result of which is the formation of nitrogen oxides. Narrowing the effective combustion temperature profile (increasing the lower temperature limit of the flame) reduces the formation of carbon monoxide.

 Reducing the viscosity characteristics of the air supplied to the combustion chamber, decreasing the drag coefficient (friction), facilitating air desorption from the elements of the turbine apparatus of air compressors reduces the power take-off for the drive.

 The effectiveness of the method is confirmed by the results of numerous tests during operation of various engines.

 When testing a diesel engine, the emitter was located on the cover of the high pressure fuel pump. The obtained results show that treatment with an electromagnetic field with specified parameters positively affects the process of fuel injection, mixture formation and combustion in the engine, improving its economy and reducing emissions of toxic basic gaseous components.

 Tests for the electromagnetic treatment of a carburetor internal combustion engine were carried out on the basis of the GAZ-24-10 car. The emitter was installed directly in contact with the car body. The charge from a single treatment accumulated on the external and internal surfaces of the metal parts of the car, including the engine, fuel line and gas tank. Processing was carried out for 48 hours, after which the charge lasted up to 10 days.

 In relation to gas transportation processes using electromagnetic catalysis, the tasks of optimizing the combustion of fuel gas, reducing toxic emissions, and facilitating gas transportation are being solved.

 The optimization of the combustion process is explained, in particular, by the fact that fuel gas, air supplied to the combustion chamber, under the influence of electromagnetic catalysis, change their viscous properties: internal friction of gas, gas friction on the wall of the pipeline or design elements of a turbine unit - blade apparatus of axial compressors, centrifugal process gas blower. As a result of changes in the aggregate viscosity properties of gas and air and their secondary manifestation — diffusion, interdiffusion, the mixture of gas and air becomes more uniform in composition. As a result, the number of zones of local overheating decreases, the effective profile of the combustion temperature narrows (the lower limit of the flame temperature rises), which has a beneficial effect on reducing harmful emissions. Reducing the viscosity characteristics of the air supplied to the combustion chamber, reducing the coefficient of friction resistance, facilitating air desorption from the elements of the turbine apparatus of air compressors reduces the power take-off for the drive of air compressors. Similar phenomena under the influence of electromagnetic catalysis also occur in gas transportation processes, which reduces the power consumption consumed by a centrifugal supercharger and further reduces fuel gas consumption.

 The application of this method will significantly reduce fuel consumption during operation of various heat engines, including internal combustion engines, and will also have a positive impact on the environment, as it will reduce the formation of harmful combustion products, such as nitrogen oxides, carbon monoxide.
