Abstract: <P>PROBLEM TO BE SOLVED: To provide a muffling device of a combustor having a large degree of freedom in the design of a flow passage size, capable of providing high muffling effects, and enabling a reduction in flow passage resistance in the ignition of the combustor.  <P>SOLUTION: This muffling device of the combustor fitted to the exhaust tube of the combustor comprises an exhaust gas flow passage for passing, therein, the exhaust gas exhausted from the combustor, an expansion hollow formed by enlarging the cross sectional area of a part of the exhaust gas flow passage in a stepped state, and a plurality of exhaust gas inflow ports formed at the exhaust gas inflow side of the expansion hollow. By this, the high muffling effects can be provided since sonic wave with large frequency generated from the combustor can be efficiently attenuated. Also, since the sonic wave with high frequency is efficiently attenuated by complicated resonance, the length of the expansion hollow can be shortened less than that of a normal resonance type muffling device. In addition, since the plurality of exhaust gas inflow ports are formed, the exhaust gas resistance of the muffling device in the ignition of the combustion can be reduced. Accordingly, the ignition of the combustor can also be smoothly performed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
