Volatile organic compound burner

A volatile organic compound burner, comprising:

• a pre-heating bushing internally circumferentially defining a receiving space and outwardly provided with a pre-heating bushing casing, the pre-heating bushing casing having air inlet outer holes for admitting combustion-enhancing air, the air inlet outer holes being in communication with the pre-heating bushing, the pre-heating bushing being conducive to pre-heating the combustion-enhancing air, cooling the volatile organic compound burner, and recycling heat;
• a porous medium comprising a heat-storing porous medium and a pre-heating porous medium, the heat-storing porous medium recycling most of heat of a flame and maintaining temperature, and the pre-heating porous medium recycling a portion of the heat of the flame, pre-heating, and preventing tempering;
• a burner body disposed in the receiving space and comprising a burner wall defining a combustion chamber and a mixing chamber, the mixing chamber having air inlet inner holes in communication with the pre-heating bushing, with a nozzle disposed between the mixing chamber and the combustion chamber, the burner wall having an organic gas inlet for admitting a harmful volatile organic compound (VOC) and a combustion gas outlet for discharging the volatile organic compound to be oxidized at a high temperature to produce carbon dioxide and water, with the heat-storing porous medium disposed between the combustion chamber and the combustion gas outlet, with the pre-heating porous medium disposed between the nozzle and the combustion chamber, the volatile organic compound, in form of different or different mixtures of volatile organic matter, entering, via the organic gas inlet, the mixing chamber to mix sufficiently therein with the combustion-enhancing air pre-heated by the pre-heating bushing to become a combustible volatile organic compound, wherein the combustible volatile organic compound passes through the gradually-widening nozzle to expand and mix to become a uniform combustible volatile organic compound, wherein the uniform combustible volatile organic compound passes through the pre-heating porous medium to undergo heat exchange with the pre-heating porous medium such that the combustible volatile organic compound gets heated up before entering the combustion chamber, wherein an arc generated by electric power ignites the combustible volatile organic compound in the combustion chamber, allowing the combustible volatile organic compound in the combustion chamber to be oxidized at a high temperature to produce carbon dioxide and water that meet emission standards, wherein the carbon dioxide and water thus produced pass through the heat-storing porous medium before being discharged from the combustion chamber via the combustion gas outlet;
• and
• an ignition electric power source having a high-voltage ignition electrode electrically coupled to the combustion chamber through a high-voltage power supply and a power switch connected between the high-voltage power supply and the high-voltage ignition electrode, wherein the power switch can be turned off to start the ignition electric power source, allowing the high-voltage power supply to provide electric power to cause the high-voltage ignition electrode to discharge and generate the arc.
