PURPOSE: To provide an air-cooled burner nozzle in which the durability of a burner nozzle installed at a burner air box of a combustion device such as a boiler or the like is improved.

CONSTITUTION: In an air-cooled burner nozzle 21 fixed to a burner end furnace side of a burner air box of combustion device arranged at the furnace through a pivot pin 22, rotated in a vertical direction or fixed at a predetermined angle, the pivot pin 22 is formed with a hollow hole 22a for feeding cooling air. An air feeding pipe 25 communicating from the fixed part of the burner nozzle 21 near the pivot pin 22 to the extremity end of the burner nozzle 21 is provided, and a cooling air reservoir 26 having a plurality of small holes 27 is disposed near and inside the furnace of the burner nozzle 21. Cooling air is fed from a hollow hole 22a to the cooling air reservoir 26 through an air feeding pipe 25, the cooling air is injected out of the small holes 27 so as to cool the extremity end of the burner nozzle 21.
