Abstract: A method and arrangement for supplying a waste heat exchanger with exhaust gas from a gas turbine are provided. The exhaust gas is guided through a diverter having a pivotable butterfly valve. When the valve is opened for initial entry of gas into the exchanger, the gas flows about the free edge of the valve. At least during initial entry of gas into the exchanger, the stream of gas is at least partially deflected downstream of the butterfly valve. This deflection is preferably eliminated after the initial entry of gas into the exchanger.

Abstract: A valve, especially a switch-over valve for large channel cross sections, is provided. A wing is pivotably mounted in a housing having channel connections. A fixating lever assembly provides for movement of the wing and includes a fixating lever and at least one link rod, one end of which is pivotably connected with the fixating lever while the other end is pivotably connected with the wing. A respective driver passes through and is mounted on opposite side walls of the housing. An inner end of each driver is connected to the fixating lever of a given one of the assemblies. A rotary drive mechanism engages an outer end of each driver.
