Definitions

  • the present invention relates to a burner using plasma in which a mixture fuel can be used as a combustion fuel, thus heating a boiler or the something with a cheaper fuel, with the mixture fuel being made by mixing water and industrial waste oil at a proper ratio.
  • the present invention is basically directed to using a burner using plasma characterized in that a combustion tank helping spray a mixture fuel via a nozzle and combust the same is designated as a positive electrode (+), and a rod installed at one side of the same is designated as a negative electrode ( ⁇ ), thus receiving a DC (Direct Current) electricity of a DC electricity supply part, and a steam supply pipe is installed, so a mixture fuel supply pipe surrounding a combustion tank in a coil shape can be heated or preheated in such a way to heat an inner wall of the combustion tank by means of a high temperature plasma flame of above 800° C.
  • a combustion tank helping spray a mixture fuel via a nozzle and combust the same is designated as a positive electrode (+)
  • ⁇ negative electrode
  • a fuel in a combustion chamber with the aid of a flame generation of a high temperature steam plasma torch from a steam supply pipe, and a fuel can be supplied at a pressure above 50 atm by a high pressure pump as a nozzle of a mixture fuel supply pipe is ignited, so the mixture can be more effectively combusted as compared to a simply spray combustion which uses a nozzle in a combustion chamber of a combustion tank owing to a high pressure and a high temperature of above 800° C., and a more continuous, safer combustion might be achieved at a lower cost in the event that a plasma torch part is used together.
  • 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.
  • 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 O 2 , H and OH-group, and the serious contamination substances contained in the waste oil can be stabilized using hydrogen fluoride, hydrogen chloride, CO 2 , 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.

  • 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.
  • a high heat is generated and is burnt on the basis of complete combustion.
  • 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.
