The hydrogen-oxygen mixed gas (HHO gas) is produced by electrolysis of water. The hydrogen-oxygen mixed gas can be combusted in a closed space without air, and since harmful substances are not generated during combustion, It is known to be able to.

In addition, the hydrogen-oxygen mixed gas may have a pin point phenomenon (a phenomenon that all the heat collects at the end of a flame as the flame becomes thinner) upon combustion, and the end of the flame may rise above 1900 ° C. There is a characteristic that it is possible to dissolve most materials by burning and burning while causing thermal fusing phenomenon.

However, since the hydrogen-oxygen mixed gas has a high temperature at the end portion of the flame due to the pin point phenomenon, the temperature around the flame is not so high, so its use is restricted for applications other than welding.

In addition, when the conventional fuel, that is, LPG, LNG, or OIL, is mixed with the hydrogen-oxygen mixture gas, the high temperature is formed by the combustion reaction with the existing fuel, thereby partially combusting the fuel particles.

However, it can be concluded that the fuel made by mixing the existing fuel and the hydrogen-oxygen mixture gas is high in efficiency and economically superior, but it is pointed out that the environmental problem due to the use of fossil fuel can not be solved fundamentally.
