Zusammenfassung:	PURPOSE:To rarefy a premixed gas by a method wherein a premixing passage air inlet is formed into a large number of small holes, and the air is dispersed to upstream and downstream premixing passage wall surfaces of a fuel nozzle. CONSTITUTION:A fuel 21 for premixing is jetted into an annular premixing apparatus 12 from a fuel nozzle 8. In the meantime, air 52 for premixed combustion is jetted from a large number of air holes 53 which are provided on the premixing apparatus, and flows into the premixing apparatus 12 as a jet stream, and is mixed with the fuel for premixing which is jetted from the fuel nozzle, and thus, a premixed gas is formed. By forming the premixed gas in this manner, not only a kinetic energy of the fuel but a kinetic energy of the air can also be utilized as an energy for the mixing, and for this reason, the mixing is accelerated, a uniform premixed gas can be obtained, and it is effective for the reduction of NOx.
