Description

Brown Gas Combustion Air Jet Burner

The present invention relates to a brown gas combustion air jet burner, which will be described in more detail, which is supplied by a compressor to the inside of the mixing chamber in order to prevent backfire or flashback which occurs during the combustion process of brown gas. The present invention relates to a brown gas combustion jet burner having an air jet nozzle for injecting compressed air and capable of supplying an appropriate amount of air to the cooling air inlet in order to prevent overheating of the injection nozzle during combustion.

Brown gas is obtained by electrolysis of water, and its combustion is a pollution-free fuel that is completely burned by its own oxygen contained in brown gas. Since no technology for mass production and a burner capable of burning the Brown Gas have been proposed, it is used only for thermal processing such as welding, cutting, soldering and brazing by Torch.

Unlike fossil fuels such as acetylene, propane and butane, Brown Gas has a high combustion speed, so when using a conventional burner, backfire or fresh back often occurs, which causes a "pop" and a loud sound to go out. Because of this phenomenon, the existing burner cannot burn Brown gas well.

As is well known, back fire occurs when the hole in the torch tip is too large, or when the gas pressure is less than the revolving combustion rate, and also when the tip is heated. Flash Back is a phenomenon in which a flame is not seen outside the tip, combustion occurs in the torch, a strange sound is heard, and sometimes a backfire occurs.

However, in case of brown gas, there is no risk of fire or explosion since the volume of the gas decreases to 1/1860 at the same time as the internal pressure of the low pressure due to the phenomenon of implosion, and the vacuum is turned off.

As such, even if there is no risk of fire and explosion, Brown Gas has a high flame speed. Therefore, it is pointed out that the combustion cannot continue because the flashback or flashback phenomenon frequently occurs. It also surprises people.

In addition, the flame of Brown Gas has a characteristic of forming a pin point as the length of the flame is formed by the improvization characteristic, and the Brown Gas flame has a unique characteristic of reacting hydrogen and oxygen in atomic and molecular states. Since hydrogen and oxygen atoms penetrate into the nucleus of the material to be heated, the material heated by thermonuclear reaction by hydrogen and oxygen is heated by hot flame when gas burns alone in the air.

Due to the unique characteristics of Brown Gas, the existing gas burner which is generally used is not suitable for burning Brown Gas, so it is possible to continuously burn in consideration of Brown Gas characteristics and to have a burner without any inconvenience to users. It is becoming.

The present invention has been proposed to eliminate the above problems and the like, the brown gas generated in large quantities by the "Brown gas mass generating device (application number: 1998-44586) including the presently filed electrolytic cell. The present invention is to propose a burner that can be used in a wide range of boilers, furnaces, stoves, etc., the object of the present invention is to prevent the backburning phenomenon or the flashback phenomenon during the combustion of Brown gas to enable continuous combustion and safe use In order to slow down the combustion speed of brown gas, compressed air is mixed into brown gas.Because it is not combustion air, it is a brown gas combustion system employing an air jet method that supplies a small amount of compressed air by a compressor. To provide an air jet burner.

Another object of the present invention is to provide a brown gas combustion air jet burner that can prevent the backfire due to overheating by supplying overheat prevention air to the outer periphery of the injection nozzle in order to solve the cause of the backfire due to overheating of the head nozzle have.

Another important object of the present invention is to install a heat plate at the end of the flame in order to apply the improvization characteristics and thermonuclear reaction characteristics of Brown gas, by heating it to dissipate heat can be obtained synergistic effect of generating energy To provide a brown gas combustion air jet burner.
