Summary:PURPOSE: To provide a method for burning for generating less NOx and the structure therefor. CONSTITUTION: Diffusion burning first fuel nozzle 131 and a swirler 151 are provided at the center of the end of an inner cylinder 181. Annular premixing chambers 152, 153 and fuel supply fuel nozzles 132, 133 are provided at the outer periphery to stably burn dilute premixed gas by flame stabilizers 162, 163. Premixing fuel supply fourth fuel nozzle 135 is provided at the outer peripheral air passage of an inner cylinder 182, and fuel is premixed with the cooling air of the air cylinder. As a result, fuel air ratio or flame temperature can be reduced in the burning area of the upstream side of the inner cylinder, thereby largely reducing NOx.
