Abstract: The muffler for the exhaust of a gas turbine is stationary with a horizontal (7) and a vertical (8) section. In the vertical section are several vertical sliding baffle plates, and there is an equal number of bent guide elements (5) arranged across the diagonal between the two sections, the gas flow being between them. The guides and sliding baffle plates touch so that continuous flow channels are formed. Alternatively, the baffle plates may all end in a horizontal plane, leaving a diverging flow space between the exit of the guide elements and the baffle plates. The vertical section has a greater cross-sectional area than the horizontal section. ADVANTAGE- Compact inexpensive design with low losses.
