Combustor and gas turbine including the same

A combustor comprising:

• a burner including a tubular nozzle casing, a head plate coupled to an end of the nozzle casing, and a plurality of nozzles to inject fuel and air,
• wherein each of the nozzles comprises outer nozzles and an inner nozzle installed inside the outer nozzles,
• each of the outer nozzles comprises a nozzle tube configured to provide a channel through which air and fuel flow, and a nozzle shroud configured to surround the nozzle tube,
• a flow distribution member is installed between the head plate and the nozzle shroud to distribute a flow rate of air introduced into the outer nozzle, and
• the flow distribution member comprises an induction plate and a distribution plate obliquely bent from an inner end of the induction plate.

A gas turbine comprising:

• a compressor configured to compress air introduced from an outside;
• a combustor configured to mix fuel with the air compressed by the compressor and combust a mixture of the fuel and the compressed air;
• and
• a turbine including a plurality of turbine blades configured to be rotated by combustion gas produced by the combustor,
• wherein the combustor comprises:
• a burner including a plurality of nozzles to inject fuel and air;
• and
• a duct assembly coupled to the burner, the mixture of the fuel and the compressed air being burned in the duct assembly to produce the combustion gas,
• wherein each of the nozzles comprises outer nozzles and an inner nozzle installed inside the outer nozzles,
• each of the outer nozzles comprises a nozzle tube configured to provide a channel through which air and fuel flow, and a nozzle shroud configured to surround the nozzle tube, and
• a flow distribution member is installed between the head plate and the nozzle shroud to distribute a flow rate of air introduced into the outer nozzle.
