Patent ID: 7784262

Claim:
An exhaust gas guide of a gas turbine, which is situated between the gas turbine and a downstream waste heat boiler and which comprises a flow channel, which has a cross-section expanding in at least some areas in the main flow direction of the exhaust gas, having installed surfaces influencing the flow, wherein the installed surfaces are a swirl device generating leading edge swirls, which is situated in the diverging area of the flow channel and is implemented to distribute the exhaust gas flow uniformly over the flow cross-sectional area upon entry into the waste heat boiler, and wherein at least one burner is situated in the diverging area of the flow channel for generating hot exhaust gas streams and the swirl device is further implemented and oriented in such a way that the leading edge swirls generated are configured to mix the hot exhaust gas streams of the at least one burner with the remaining exhaust gas within a distance defined by the flow channel before the exhaust gas flows into the waste heat boiler.
