Description

Multi-Oil Nozzle Incineration Burner (abbreviated as “Incineration Burner”) {omitted}

The present invention relates to a multi-oil nozzle incineration burner, in which various oils are heated in a primary preheater and then mixed with an oil / water separator or an emulsion zone. After heating with a two-circuit oil heater, the evaporator is vaporized in the final vaporizer line in the furnace and pressurized discharge, turning, vortexing, stirring, and burning to prolong the residence time of the flame, increasing the temperature in the furnace up to 1,400 ℃. The present invention relates to a multi-oil nozzle incineration burner that is satisfied to stay at least 1 second (2 seconds or more depending on the capacity) in an incineration furnace high-temperature pyrolysis facility in an air preservation method that is not feasible with a conventional burner.

An object of the present invention is to burn by pressurized spraying with a nozzle for the reason that it is impossible to burn completely in a general burner. The purpose of the spray is to ignite and burn the gas, which is gasified by heat, rather than burning it directly from the liquid. I'm trying to speed up. However, gasification requires some time to vaporize the liquid instantaneously because it immediately meets cold air even when sprayed with warmed oil, and it occurs momentarily in the furnace chamber because it is vaporized by the heat of the flame. Therefore, it is a cause of unburned.

Therefore, this incineration burner is completely vaporized in a constant incineration furnace space and hot air and dilute swirling vortex agitated combustion, so the vaporized gas cannot be a liquid at any moment, and the temperature inside the furnace is raised up to 1,400 ℃, which is impossible with conventional burners. The purpose of the invention is to completely burn out various harmful substances in the incineration burner, so that even if the abnormal conditions in the firebox are completely burned.

The diesel injection nozzle 7 has a double ignition protection cup attached to the tip of the nozzle to prevent misfire due to the strong air discharged from the turbo fan 43.

The inner circumferential surface of the first burning chamber 53 of the incineration burner 53 is coated with zirconia ceramic to prevent surface erosion due to disulfide gas, acid gas and thermal shock generated during waste oil combustion.

2, the inner circumferential surface of the first combustion chamber is made of a castable refractory 26, the outer circumferential surface is covered by a heat insulating material 27, the waste air heat jacket 24 is formed on the outer circumferential surface and the preheated air The turbofan is sucked into the hot air required for the primary combustion chamber.

The temperature of the aspirated air is 90 to 120 ° C. to suppress the liquefaction of the already vaporized waste oil. At this time, the intake air temperature control is determined by the thickness of the insulation.

The high pressure air is blown out by the open fallopian tube 54 to push the internal pressure of the existing boiler to protect the flame.

In order to eliminate the blockage of the condensation in the pipe in using the oil which is hardened at low temperature during the non-operational use of the various oils, the return circuit is circulated by the three-way valve 43, and at this time, even when the oil pump is operated, the electric valve (11) is closed, and special high temperature heating wire is attached to all pipes.

The anthocyanyl-nozzle incineration burner according to the present invention configured as described above operates as follows. In the initial operation, the diesel oil stored in the diesel oil storage tank (1) is preheated by the gear pump 12 through the two-circuit oil heater (3), and then supplied to the diesel oil burner (7) to automatically ignite to form an initial flame. At this time, the double ignition protection cup (FIG. 2: 51) protects the flame and prevents misfire due to the strong air ejected from the high-pressure blower, and the main oil flows into the oil pump 12 at 100 ° C or higher and lower than 200 ° C. The oil of the oil storage tank 9 is supplied to the preheating jacket 14, and the preheated oil is heated in the two-circuit oil heater 3 through an oil separator or emulsion zone 18 so that the oil pump 12 is low speed. Part of the furnace is bypassed to the oil storage tank 9 by a three-way valve. The reason for the bypassing is because of the expansion pressure due to heat when the temperature in the two-circuit oil heater 3 rises. Then, when the temperature in the incineration burner furnace rises and becomes the optimum temperature for burning the injection oil, the three-way valve Is converted to the vaporization line of the multi-burner and the oil is supplied. The gas is supplied from the vaporization line to the first combustion chamber in a vaporized state so that complete combustion is induced, thereby easily forming a flame. The light ignition burner is automatically extinguished when it is higher than 150 ℃ above the pre-ignition temperature.

The primary flame is orbital combustion in the primary combustion chamber and the combustion air is used as the intake combustion air by the turbo fan in the air waste heat absorption space, thereby reducing the combustion time. By the primary flame induction member, the combustion is reburned in the secondary combustion chamber by swirling, vortexing, stirring, and jet nozzles in contact with oxygen again, and the secondary flame induction member causes combustion in the tertiary combustion chamber like the previous combustion chamber. In the third combustion chamber, the windbox air is pressurized and supplied to the discharge flame by the trumpet pipe to protect the flame from the internal pressure of the final flame discharge port. It will show the row's flame color.

As described above, the multi-oil-nozzle incineration burner according to the present invention preheats the oil before the oil flows into the combustion chamber, separates or dilutes the oil and water from each other, and heats and vaporizes the oil in the combustion chamber again, so that the flame is generated by the vortex generator. Pressurized discharge vortex vortex agitation occurs and the outer flame is pressurized and discharged into the wall of the combustion chamber inner circumferential surface by rotating projections that change the direction of rotation of each opening hole. Given that combustion is complete and the conventional combustion efficiency is 85% on average,

☞ 13% oil savings with 98% efficiency when using multi-vana

☞ Prevents premature corrosion of boilers and extends life due to no sulfur dioxide and sulfuric acid

☞ Solution of high temperature pyrolysis of various dioxins and heavy metals

☞ If oil is sprayed by the nozzle, the nozzle will be blocked to prevent economic losses such as downtime.

There is an effect of two stone that can solve the above points.
