EXHAUST GAS TURBINE AND METHOD OF CONTROLLING THE TURBINE

摘要

In an exhaust gas turbine with a guide section for the exhaust gas turbine comprising a flow-through duct for conducting exhaust gas through the exhaust gas guide section, wherein the flow-through duct includes a wheel chamber in which a turbine wheel is rotatably supported and wherein, downstream of the wheel chamber, the flow-through duct has an outlet portion and upstream of the wheel chamber, the flow-through duct has an inlet portion with a bypass duct being formed in the exhaust gas guide section for by-passing the wheel chamber, the by-pass duct forms an annular opening adjacent the turbine wheel for directing by-pass exhaust gas into the exhaust gas outlet portion in an annular flow pattern along the outlet portion duct wall.

1. An exhaust gas turbine with a flow guide section (1), comprising a flow-through duct (3) which includes a turbine wheel chamber (6) in which a turbine wheel (7) is rotatably supported, an inlet section (4) upstream of the turbine wheel chamber (6) and an exhaust section (5) at an exit end (11) of the turbine wheel chamber with a conical sleeve (19) movably disposed in the exhaust section (5) and forming at its front end adjacent the turbine wheel exit end (11), a bypass duct (15) extending from the inlet section (4) to an annular bypass flow opening (16) for directing by-pass exhaust gas into the exhaust section (5) downstream of the wheel chamber (6), the by-pass flow opening (16) with a flow cross-section (17) forming a by-pass passage into the area of the exit end (11) into the exhaust section (5).
