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.

Abstract: PROBLEM TO BE SOLVED: To ensure a simple and compact structure by connecting a main gas annular conduit with a main gas supply pipe line upstream and connecting a pilot gas annular conduit with a pilot gas supply pipe line upstream, and connecting the main gas annular conduit and the pilot gas annular conduit with an annular combustor downstream. SOLUTION: A main gas annular conduit 13 and a pilot gas annular conduit 14 are connected with a main gas supply pipe line 15 or a pilot gas supply pipe line 16 upstream, respectively, and are connected with an annular combustor 1 downstream. In operation of a gas turbine main gas introduced into the main gas annular conduit 13 through the main gas supply pipe line 15 and the pilot gas supply pipe line 16 and pilot gas introduced into the pilot gas annular conduit 14 are distributed to a main gas pipe 18 and a pilot gas conduit 19 of a double cone burner 4 in a pressure resistant burner hood 3. All connection parts of the fuel pipings are welded to improve reliability of the operation of the gas turbine.
