Description

Brown gas burner for burning promotion

The present invention relates to a brown gas burner for promoting combustion, and specifically, a certain amount of space is secured to the outer circumference of an oil nozzle supplying oil to vortex brown gas mixed with compressed air (hereinafter referred to as "BG mix air"). The present invention relates to a combustion-promoting brown gas burner capable of supplying fuel to the point where oil is injected and promoting combustion, thereby reducing fuel consumption and pollution.

In general, the combustion chamber that burns fossil fuel is required to blow the primary air and the secondary air to burn the fuel, and the combustion gas generated in the combustion process is discharged to the chimney.

By the way, it is true that banca-C oil is disappearing into the chimney due to incomplete combustion because it is difficult to burn completely.

Therefore, in order to improve combustion efficiency, various air-mixing devices are being developed and efforts are being made to recover heat disappearing into the chimney. However, technically, they are at the limit and waste valuable energy resources.

In addition, due to environmental issues, banca-C oil is strongly restricted from being used in six cities. Moreover, crude oil refining, such as banca-C oil, has no choice but to be discarded without any countermeasures. The problem is being pointed out.

The present inventors have focused on this point, and as a result of mixing the brown gas with the oil fuel and supplying it to the point where the oil is injected and burned, the present invention has been proposed to focus on the complete combustion can occur.

As is well known, brown gas is obtained by electrolysis, and refers to a mixed gas in which hydrogen and oxygen are mixed in a ratio of 2: 1, as shown in the following structural formula.

Brown gas, which has a structural formula of 2H2O → 2H2 + O2, is not only a completely pollution-free fuel, but also has an implosion and thermonuclear reaction characteristic of Brown gas, unlike hydrogen gas.

The brown gas generator that produces this brown gas produces about 1860 liters of brown gas with one liter of water. On the contrary, when 1860 liters of Brown gas is burned by a spark in a sealed pressure vessel, the pressure drops as soon as the pressure peak reaches 0.5 MPa for 44 seconds of the explosion duration. As the volume decreases, a vacuum is created (ie 1 liter of water is produced again and the remaining volume is vacuumed).

This is described as Implosion, a concept completely different from Explosion.

Brown's flame is a state in which the improvisation is continuing. Therefore, the brown gas flame forms a pinpoint flame, and the shape of the flame is long, and the heat accumulation is small, but the ceramic, which is a heat-resistant material, also melts in the pinpoint portion, thus showing a strong firepower capable of drilling the flame.

Brown's gas flame also has a unique characteristic of reacting hydrogen and oxygen in atomic and molecular states. Hydrogen atoms and oxygen atoms penetrate into the nucleus of the material to be heated. Therefore, the material heated by thermonuclear reaction by hydrogen and oxygen is heated by the flame much hotter than the flame when the gas burns alone in the air.

Brown gas, which has different thermonuclear reaction characteristics depending on the material to be heated, can weld brick and iron as it is.

Brown gas, which has such unique characteristics, is composed of hydrogen, which is the most burning fuel, and oxygen, which is a supporting agent, so that the incomplete combustion portion can be converted into complete combustion simply by putting it in the existing combustion chamber.

However, if Brown gas is supplied to the combustion chamber by a separate nozzle, the nozzle will catch fire and there is no effect of promoting the combustion. Therefore, fuel must be supplied to the central point where it is sprayed.

In fact, when oil burns, H2 in the fuel burns first in the center of the flame. Injecting Brown gas as described above is very effective because it supplies H2 to the center of the flame.

In addition, in order to achieve the object of the present invention, brown gas must be supplied in large quantities.

Therefore, the present invention is possible because the "Brown gas mass generating device including a row type electrolytic cell" (patent 275504; hereafter referred to as "brown gas generator") developed and filed by the applicant can be supplied in large quantities. In addition, the present invention not only can reduce enormous energy costs by the brown gas combustion promotion method by producing a brown gas burner capable of effectively injecting brown gas, but also fundamentally removes pollutants such as NOx, Sox, and CO2 dust. It can be reduced to.

The present invention is to use the brown gas generated in the brown gas generator as a fossil fuel oil, boilers, boilers, etc. extensively for complete combustion to minimize the waste of fuel and the emission of pollutants due to incomplete combustion. It is to provide a brown gas burner for fuel promotion.

In order to provide said burner, the following matters must be considered technically.

In addition, brown gas, unlike fossil fuels, has a high combustion speed and must be considered to prevent backfire or flashback.

In other words, a method of mixing brown gas into the atomizing compressed air should be adopted as a method for slowing the combustion speed of brown gas so that it can be continuously burned completely by preventing backfire or flashback during the supply of brown gas.

In addition, since the working pressure of the brown gas generator is 1 kg / cm 2 or less, a method of incorporating brown gas into a compressed air of higher pressure should be taken.

The important thing in the burner is that the oil has to be sprayed, so when the oil is sprayed from the spray nozzle and ejected from the tip through the oil spray pipe, it is necessary to supply an appropriate swirler to supply an effective spraying condition by supplying BG mix air. Must be installed.

Also, in order to effectively supply the combustion air from the windbox, a plurality of first air supply ports may be installed so as to peak on the center line of the oil spray pipe, and the majority of the combustion air is supplied to the second air supply. The method of supply through the air supply port should be devised.

The overall configuration of the present invention completed in consideration of this point is the chamber and one end portion for supplying the BG mix air mixed with compressed air and Brown gas by the oil filling chamber and the mixer to store the oil supplied from the oil supply pipe in the inner center A housing in which the flange portion is integrally provided; An oil spray gun mounted on the oil filling chamber and spraying oil into the combustion chamber; A BG burner gun for supplying a BG mix air in a vortex form on the center of the oil sprayed to the chamber; A wind box for supplying external air to the combustion chamber to promote combustion; Located in the front end of the BG mix air spray pipe is composed of a burner tile for supplying air to the combustion chamber through the first air supply port and the second air supply.
