ABSTRACT:
A gas turbine power plant has an arrangement for collecting coolant fluid exiting from fluid-cooled turbine buckets in the gas turbine. The buckets have radially extending internal coolant passages arranged to discharge coolant from the outer ends of each bucket. The arrangement for collecting the coolant exiting from the buckets comprises an annular chamber within the casing aligned with the buckets. A slotted annular wall is interposed between the chamber and the buckets, with the wall forming the entrance for discharged coolant fluid into the chamber. The wall has a plurality of adjacent sharply angled faces forming the annular inner surface and has slotted passages extending angularly and radially through the wall at the converging bases of adjacent angled faces. The angled faces of the inner surface diffuse the impact of the coolant fluid and direct the fluid to the passages and into the chamber.
