Abstract:
1. A power plant comprising: a first turbine having a plurality of turbine stages, the first turbine discharging a first fluid flow; a second turbine operatively coupled to the first turbine, the second turbine receiving the first fluid flow from the first turbine and a second fluid flow; an interface member mounted between the first and second turbines, the interface member including a main body portion having an inner surface, an inlet portion and an outlet portion that combine to form a fluid flow path that extends between the first and second turbines, an input member provided on the main body portion between the inlet portion and outlet portion, the input member including an input passage that leads the second fluid into the fluid flow path, and a baffle plate extending about at least a portion of the inner surface of the interface member toward the fluid flow path, the baffle plate including a first end section that extends from the inner surface to a second end section that is spaced from the fluid flow path to establish a non-uniform radial flow gap extending about the main body portion and an axial flow gap between the input passage and the inlet and outlet portions that elevate residence time of the second fluid in the interface member.
