Burner using plasma

Abstract

The present invention relates to a burner using plasma, which uses a mixture fuel in which water and industrial waste oil are mixed at an appropriate ratio. A combustion tank has a positive electrode (+), a rod installed at one side of the combustion tank has a negative electrode (−), and direct current electricity is supplied to the combustion tank and to the rod from a direct current electricity supply unit. A steam supply pipe of a steam generator is installed together with a plasma torch unit which is coupled to the combustion tank, such that high-temperature steam is discharged from the steam supply pipe together with the plasma torch generated by the plasma torch unit. Thus, the high-temperature plasma torch generates a high-temperature plasma flame of 800° C. or higher to heat a combustion chamber at the inner wall of the combustion tank. A mixture fuel supply pipe is wound into a coil on the outer surface of the combustion chamber, such that the mixture fuel supply pipe is preheated by high-temperature heat. The mixture fuel in the mixture fuel supply pipe is supplied at an air pressure of 50 through a high pressure pump, and water in the mixture fuel is decomposed into hydrogen and oxygen and waste oil in the mixture fuel is decomposed into carbons. The mixture fuel is injected or sprayed through a nozzle at a high temperature to effectively and completely burn the mixture fuel. The plasma torch unit operates by means of the direct current electricity supplied by the direct current electricity supply unit if needed, to adjust the temperature of the combustion chamber of the combustion tank, thereby enabling the smooth use of the burner.

AI Technical Summary

Benefits of technology

[0010]As described above, the burner using plasma according to the present invention is characterized in that a combustion tank 1 configured in such a way that a mixture fuel supply pipe 3 is wound in a coil shape on an outer surface of a combustion tank 1, is designated as a positive electrode part 7, and a rod engaged at an outer side of the same is designated as a negative electrode part 8, so a direct current electricity is supplied from a direct current electricity supply part 6, and a steam supply pipe 13 serving to receive steam from the steam generation part 12 is disposed between the combustion tank 1 and the negative electrode part 8, thus forming a plasma torch part 9, so a flame of a high temperature steam plasma torch is generated in the combustion chamber 11 of the combustion tank 1. In the mode of the activation, a high temperature plasma flame can be generated at a high temperature of above 800° C., and since the inner wall of the combustion tank is heated and consequently preheated, the mixture fuel can be supplied at a high pressure of above 50 atm, and the water is decomposed into hydrogen and oxygen in the mixture fuel supply pipe 3, and the waste oil is decomposed into carbon components. When such components pass through the nozzle 4, a high heat is generated and is burnt on the basis of complete combustion.

[0011]The mixture fuel combustion in the combustion tank 1 helps to perform a preheating combustion and to adjust the combustion state with the aid of the operation of the plasma torch part 9, thus always achieving complete combustion, and the water in the mixture fuel is decomposed into hydrogen and oxygen, and the waste oil therein is decomposed into carbon components, so the air contamination due to the waste oil can be significantly filtered and prevented, thus achieving an economically advantageous effect.

Problems solved by technology

The oil burner generally used at a boiler or the something is designed to use a relatively expensive fuel oil and to spray via a nozzle in a mist form, thus combusting the fuel; however the maintenance of the boiler is costly which leads to a higher economic burden to a user.

To overcome the above problems, an industrial water oil is being suggested as a fuel; however the production of the industrial waste oil is very limited, thus limiting its actual application.

Since diverse contaminations are contained in the waste oil, without a high temperature combustion, a harmful gas generated during an incomplete combustion could contaminate air.

When it is needed to properly process such harmful gas, a high temperature heat decomposition process is needed at each step, and the industrial waste oil is needed to be processed in a mixing chamber which decomposes the oil into O2, H and OH-group, and the serious contamination substances contained in the waste oil can be stabilized using hydrogen fluoride, hydrogen chloride, CO2, etc; however the decomposition process system of such serious contamination substances require very expensive further facilities and high operation costs, which substantially retards the applications.

There is another conventional art characterized in that water and waste oil are mixed at a proper ratio, and the mixture fuel of water and the waste oil is sprayed via a nozzle in a mist form in a combustion chamber and is combusted in the same, and a long mixture fuel supply pipe, adapted as a means for enhancing a combustion efficiency during a spray combustion of a mixture fuel, is installed in a separate preheating chamber in a coil shape, thus enhancing a fuel spray via a nozzle in a mist form, and a combustion efficiency; however the above conventional art has some limits in that it is almost impossible to increase the mixture fuel supply pipe formed in a coil shape to a proper temperature (above 800° C.) with only the heating apparatus which is designed to exclusively heat the preheating chamber, so the spray combustion of the mixture fuel with the aid of the nozzle becomes unstable, which results in a lower combustion efficiency in the boiler owing to an incomplete combustion.
