ABSTRACT:
A gas-turbine engine combustor having a plurality of venturi mixers, each connected to an air supply path that passes air compressed by a compressor and to a supply source of gaseous fuel, which mix the air and the gaseous fuel to produce an air-fuel mixture and supply the air-fuel mixture to a combustion chamber for generating premixed combustion or diffusive combustion such that produced combustion gas is supplied to a turbine through a turbine nozzle to rotates the turbine that outputs its rotation through an output shaft, while driving the compressor by the rotation. The combustor includes a casing which defines the combustion chamber, and a liner disposed at an outer side of the casing to be communicated with the turbine nozzle, wherein the liner is formed with a plurality of holes through which a part of air passing through the air supply path enters the outer side of the casing, thereby enabling to cool the combustion chamber casing effectively, without introducing a flesh air or a diluted air into the combustion section of the combustion chamber, while ensuring the strength and durability of the combustion chamber casing.
