1. A method of cooling at least one joint flange bolt used with a rotary machine, said method comprising:
extracting working fluid having a first temperature and a first pressure from a location of the rotary machine, wherein the first temperature is lower than an operating temperature at a first joint flange bolt hole defined in a casing of the rotary machine; diverting a first portion of the extracted working fluid into a first supply hole defined in a lower section of the casing, wherein the first supply hole is in flow communication with a first clearance gap defined between an interior surface of the first joint flange bolt hole and an exterior surface of the joint flange bolt installed in the first joint flange bolt hole; exhausting the first portion of extracted working fluid through a first exhaust hole defined in an upper section of the casing, wherein the first exhaust hole is in flow communication with the first clearance gap, such that the first portion of extracted working fluid flows around the exterior surface of the joint flange bolt; and routing the first portion of the extracted working fluid into a first conduit in flow communication with the first exhaust hole, such that a first flow path is defined from the working fluid extraction location of the rotary machine, through the first clearance gap and first exhaust hole, to the first conduit. |
