  "textContent": "One or more cooling systems (100, 102, 104) for ventilating a turbine (20) and rotary shaft (14) of a gas turbine system (10) is provided. The gas turbine system (10) includes a gas turbine engine (12) and a turbine exhaust collector (13) in separate enclosures (2, 3). A first cooling system (104) includes an educator (72) that sucks exhaust gas through a diffuser (41) and directs it out of the turbine exhaust collector enclosure (3) based on suction pressure created from the high velocity of exhaust gas. A second cooling system (102) include struts (98) that enable the exhaust gas to flow from the diffusers (41) to a ventilation flow stack (28). A third cooling system (100) includes exhaust gas sucked from an opening to a top duct (68) based on suction pressure created from the rotation of the rotary shaft (14) disposed about a coupling (48). A guideway associated with the third cooling system (100) also directs the exhaust gas to flow to the top duct (68). These cooling systems (100, 102, 104) are designed to increase the efficiency of ventilating the turbine (20) and rotary shaft (14), prevent misalignments of the rotary shaft (14), which may result in thermal stresses, and allow the use of the gas turbine systems (10) in higher ambient temperature environments.",
