PROBLEM TO BE SOLVED: To provide a mixed combustion burner device capable of reducing the number of components and being downsized with a simple structure.SOLUTION: An atomizer 36 is disposed on the central axis of a register, and a swirler 51 is disposed around the atomizer 36. A plurality of gas nozzles 65 are disposed with intervals on a virtually disposed circle 101 with the atomizer 36 as a center. In the gas nozzle 65, gas fuel is injected toward a recirculation region formed by the swirler 51, and a gas opening 66 for pilot flame is formed so as to form a pilot flame. Also, in the gas nozzle 65, gas openings 67, 68, 69, to which gas fuel is injected so as to form a main flame with the pilot flame, are formed. |
