<P>PROBLEM TO BE SOLVED: To provide a combustion device wherein a smaller air mass flow rate is made to flow from a plenum to decay volume. <P>SOLUTION: The combustion device 1 for a gas turbine comprises a portion 6 including an inner wall 7 and an outer wall 8. The inner wall 7 comprises first passages 9 connecting a zone between the inner and outer walls 7, 8 to the inner side 10 of the combustion device 1. The outer wall 8 comprises second passages 2 for cooling the inner wall 7. Between the inner and outer walls 7, 8, an intermediate layer 17 is provided defining a plurality of chambers 18, each connected to at least one first passage 9 and the plurality of second passages 12 and defining Helmholtz dampers. The second passages 12 open in third passages 22 connected to the chambers 18 and have outlets 23 facing to each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
