  • Method and arrangement for supplying a waste heat exchanger with exhaust gas from a gas turbine
    Patent number: 6919050
    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.
