Abstract
A combustion burnerA according to one embodiment of the present invention includes: a fuel nozzle; a burner tubeforming the air passagebetween the burner tubeand the fuel nozzle; swirler vanes (swirler vanes)arranged in a plurality of positions in the circumferential direction on the external circumferential surface of the fuel nozzle, each extending along the axial direction of the fuel nozzle, and gradually curving from upstream toward downstream; and a liquid fuel injecting holeA from which a liquid fuel is injected to a surface of each of the swirler vanes. The combustion burnerA also includes multi-purpose injecting holes-to-as a cooling unit that cools a part of a vane pressure surfaceof the swirler vaneon which the liquid fuel LF hits. Water is injected through the multi-purpose injecting holes-to-to form a water filmA on the vane pressure surface, whereby a combustion temperature is reduced and formation of carbon deposit is prevented.
