Patent ID: 8511088

Claim:
A gas turbine combustor adapted for combusting fuel with compressed air supplied from a compressor so as to produce combustion gas and then feeding the so-produced combustion gas into a turbine, the combustor comprising: a combustion cylinder constituting a combustion chamber; a fuel injection unit adapted for supplying the fuel to a head portion of the combustion cylinder; a support member configured for supporting the fuel injection unit in the combustion cylinder; and a heat shield adapted for heat-insulating the support member from the combustion gas in the combustion chamber, wherein the fuel injection unit includes a fuel injection valve adapted for injecting the fuel, and a swirler adapted for supplying the compressed air to the fuel injected form the fuel injection valve while swirling the compressed air, wherein the swirler and the heat shield are connected together by a connecting member, wherein the connected swirler and the heat shield constitute a swirler unit, and wherein the swirler unit is detachably attached to the support member via a fastening member, and wherein, during assembly of the combustor, the swirler unit is mounted axially downstream from a direction of the support member, and the heat shield is mounted downstream from the swirler.
