Abstract:
1. 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 rotate the turbine that outputs a rotation through an output shaft, while driving the compressor by the rotation, comprising: a casing which defines the combustion chamber; and a liner disposed at an outer side of the casing to be connected 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, while the casing being formed without a hole through which a part of air passing through the air supply path enters the combustion chamber.
