Field of the Invention The present invention relates to a burner for burning a fuel gas, and more particularly to a burner for cooking gas or a metal material such as a "burner" using a combustion flame of a fuel gas such as LNG or LPG as a heat source. It is intended to be applied in various ranges such as a heat source.

て限定的な範囲に限られ利用範囲の狭いものであった。However, in the above-mentioned conventional burner, there is a limit in obtaining a combustion flame having a high temperature, and in particular, in order to obtain a combustion flame having a strong thermal power, the combustion air ratio exceeds the stoichiometric air ratio. When a mixed gas is used, the mixed gas is diffused without igniting because the jetting speed of the mixed gas at the burner opening is too fast, or so-called lifting or the like in which a flame is formed intermittently and unstablely. There was a malfunction that occurred. For this reason, in the burner of this type, the applicable field of application is limited to a very limited range such as kitchen appliances and the range of use is narrow.
