ACOUSTIC LINER FOR GAS TURBINE COMBUSTOR

PROBLEM TO BE SOLVED: To provide an acoustic liner for a gas turbine combustor which reduces the consumption of purging air to increase the amount of combustion air burned in a gas turbine combustor, thereby lowers the temperature of combustion gas, and reduces the produced amount (the emitted amoun...

Summary:PROBLEM TO BE SOLVED: To provide an acoustic liner for a gas turbine combustor which reduces the consumption of purging air to increase the amount of combustion air burned in a gas turbine combustor, thereby lowers the temperature of combustion gas, and reduces the produced amount (the emitted amount) of NOx. SOLUTION: A housing 11b is provided with at least one purge hole 14 bored in a surface facing a wall surface of a combustion cylinder 2 wherein static pressure is increased when a gas turbine is operated, and along with the pressure increase, combustion gas in the combustion cylinder 2 is jetted into a resonance space.
