<P>PROBLEM TO BE SOLVED: To provide a dual soft passage nozzle for low combustion dynamics in premixed, low emissions gas turbines and the like. <P>SOLUTION: The fuel nozzle system 100 may include a pre-orifice for a first pressure drop, a captured response volume in communication with the pre-orifice, a post-orifice in communication with the captured response volume for a second pressure drop, and a secondary fuel passage 120 downstream of the post-orifice for a third pressure drop. The second pressure drop is less than the first pressure drop and the third pressure drop is less than the second pressure drop. <P>COPYRIGHT: (C)2012,JPO&INPIT |
