FUEL SUPPLY DEVICE FOR GAS TURBINES AND FUEL NOZZLE AND GAS TURBINE HAVING THE SAME

The present disclosure relates to a fuel supply device for gas turbines, and a fuel nozzle and gas turbine having the same. The fuel supply device of present disclosure is mounted to the fuel nozzle for a uniform flow of air introduced thereinto and for allowing uniform mixing with fuel. The present disclosure allows a uniform fuel-air mixture to be supplied to a combustion chamber. According to the present disclosure, it is possible to uniformly supply a fuel-air mixture to a combustion chamber by arranging a plurality of perforated plates in a fuel supply device for gas turbines, to suppress generation of nitrogen oxides, and to prevent flame from stagnating or flowing backward.
