Abstract
A system includes a turbine having an exhaust flow path, an inner turbine wall radially disposed along the exhaust flow path, an outer turbine wall disposed along the exhaust flow path and radially outward from the inner turbine wall, and an outer flow control vane configured to selectively extend radially inward from the outer turbine wall. A radial extent of the outer flow control vane is less than a radial distance between the inner turbine wall and the outer turbine wall. The outer flow control vane is disposed downstream of a last stage vane of the turbine and upstream of a last stage blade of the turbine. The turbine also includes an actuation assembly configured to actuate the outer flow control vane to cause the outer flow control vane to extend radially inward. The system also includes a controller configured to instruct the actuation assembly to actuate the outer flow control vane.
