Abstract
A combustion nozzle discharges compressed air and fuel, to be combusted, into a combustion chamber of a combustor of a gas turbine. The combustion nozzle includes an air inlet, a nozzle orifice, an air channel, a fuel channel, and fuel outlets. The air inlet receives the compressed air. The nozzle orifice opens into the combustion chamber and discharges the compressed air. The air channel communicates between the air inlet and the nozzle orifice. The fuel channel receives the fuel, and discharges the fuel from the fuel outlets toward a flow of the compressed air discharged from the nozzle orifice. The air channel includes a Venturi section in which a channel cross-sectional area of the compressed air becomes relatively small. The fuel outlets are provided in the Venturi section.
