Abstract: PROBLEM TO BE SOLVED: To provide a means for obtaining the complete premixing of used fuels and hence the decrease in harmful substance and emission by improving the burner for a heat generator mainly having means for forming vortex flow from combustion air and means for injecting fuel into the air. SOLUTION: A means for forming vortex flow from combustion air 9 is disposed in an annular gap 4 formed of an inner part 2 and outer shell 3. Means for forming the air 9 to the vortex flow is formed of at least one surface 5 obliquely extended to the periphery of the outer periphery of the part 2 in the gap 4, and a mixing zone 7 is disposed at the downstream side of the obliquely extended surface 5.
