FUEL NOZZLE FOR GAS TURBINE ENGINE AND METHOD OF OPERATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a system for selecting fuel without increasing installation cost and operation cost in supplying multiple kinds of fuel.SOLUTION: A fuel nozzle assembly for use with a turbine engine includes at least one fuel conduit coupled to at least one fuel source. The fuel nozzle assembly also includes at least one swirler 224 that includes at least one wall 230 having porous portions 234/236. The at least one wall 230 is coupled to the at least one fuel conduit. The porous portions 234/236 are formed from a material having a porosity that facilitates fuel flow therethrough. At least one fuel flow path is thereby defined through the porous portions 234/236 of the at least one wall. Porosity values of the porous portions 234/236 facilitate changing flow rates of different fuels according to the diffusive nature of the porous materials.
