METHOD FOR DIVERTING FLOW AROUND AN OBSTRUCTION IN AN INTERNAL COOLING CIRCUIT

摘要

A rotary machine including: a casing providing an annular chamber for rotating components of the machine; a cooling passage extending through the casing or mounted to a surface of casing; a plug assembly connected to the cooling passage and in the casing or mounted to the casing, wherein the plug assembly includes a collar and a conduit aligned with an axis of the collar, and the collar includes a cooling air by-pass passage in fluid communication with the cooling passage such that cooling air from the cooling passage flows through the by-pass passage and returns to the cooling passage, and another cooling passage or a port extending through the conduit of the plug assembly.
