Stage: PROBLEM TO BE SOLVED: To propose a structure which enables improvement of combustion efficiency of a gas fuel while inhibiting disturbance of a circular vortex and deterioration of combustion reaction in the circular vortex at a burner using the gas fuel as a supplementary fuel.SOLUTION: A burner includes a multi-walled pipe including an inner pipe and multiple outer pipes disposed at the outer side of the inner pipe, which are coaxially arranged centered on a burner axis. The multi-walled pipe has: a fuel jetting port which is disposed at a downstream end of the inner pipe and jets air-fuel mixture of a main fuel and primary combustion air which are supplied to the inner pipe; a secondary air outlet which is disposed at an outer periphery of the fuel jetting port and blows secondary combustion air supplied to a space between the multiple outer pipes; and an annular gas fuel outlet which is disposed between the fuel jetting port and the secondary air outlet and blows a gas fuel serving as a supplementary fuel and supplied to a space between the inner pipe and the multiple outer pipes to a border portion between the air-fuel mixture and flow of the secondary combustion air.SELECTED DRAWING: Figure 2 (Grant)
