Combustion apparatus and gas turbine including the same

A gas turbine comprising:

• a compressor for sucking air and compressing the sucked air to a high pressure;
• a plurality of combustors for mixing the compressed air with fuel and combusting the mixture, each combustor comprising:
• a casing,
• a pilot nozzle disposed at the center of the casing, and
• a plurality of main nozzles arranged around the pilot nozzle, each main nozzle including a first fuel channel extending to a fuel spray position of the first fuel channel and a second fuel channel extending to a fuel spray position of the second fuel channel;
• a turbine for generating electric power by rotating a turbine blade using high temperature and high pressure combustion gas discharged from the combustors;
• a pilot manifold connected to the respective pilot nozzles of the plurality of combustors and supplied with fuel by a pilot fuel supply pipe;
• and
• a main manifold connected to the respective main nozzles of the plurality of combustors and supplied with fuel by a main fuel supply pipe,
• wherein the main fuel supply pipe of the main manifold includes:
• a first fuel supply pipe supplying the fuel to a first main manifold connected to each of the first fuel channels;
• and
• a second fuel supply pipe supplying the fuel to a second main manifold connected to each of the second fuel channels.
