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.

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 substanc
