VENTURI COOLING SYSTEM

摘要

<P>PROBLEM TO BE SOLVED: To improve a cooling passageway of a venturi inside a combustor of a gas turbine. Ž<P>SOLUTION: The combustor of the gas turbine is provided having a nozzle assembly located at one end of the combustor and a combustion chamber defining a second end of the combustor. The venturi is positioned within the combustor, between a nozzle and the combustion chamber. The venturi defines a passageway therein having a first side facing the nozzle and a second side facing the combustion chamber. Compressed air is directed into an inlet in fluid communication with the first and second sides of the venturi passageway. The venturi passageway directs the compressed air from the inlet in opposite directions within the first and second sides of the passageway for cooling the venturi. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
