Arrangement for influencing an exhaust gas flow

1. An arrangement for influencing the flow of an exhaust gas of a gas turbine in a channel, comprising: a flow grating disposed transversely in the channel at an end of the channel that faces the gas turbine, wherein said flow grating continually partially obstructs the cross-sectional area of the channel, and wherein said flow grating is provided with passages, wherein the channel conveys the exhaust gas to a waste-heat exchanger or boiler further downstream of said flow grating; and a support structure, wherein said flow grating is connected to said support structure, further wherein said support structure is provided with support pipes or support rods, wherein link members pivotably securing one side of the support structure to an additional support longitudinally offset from a plane containing the flow grating, said plane transverse to the channel longitudinal axis, said additional support pivotably mounting on a wall of the channel, and wherein said support pipes or support rods are guided beyond the channel and are pivotably mounted on a wall of the channel.

2. An arrangement according to claim 1 , wherein said support pipes or support rods are mounted in a vibration-dampening manner.

3. An arrangement according to claim 2 , wherein externally of the channel, said support pipes or support rods are supported on a foundation.

4. An arrangement according to claim 1 , wherein said support pipes or support rods are supported on a framework or structure that surrounds the channel.

5. An arrangement according to claim 1 , wherein said support pipes or support rods are supported in a thermally-movable manner on a foundation or on a framework or structure.

6. An arrangement according to claim 1 , wherein said support pipes or support rods are sealed relative to the channel via compensators.
