PROBLEM TO BE SOLVED: To provide a turbine power generation system with thermal response rate matching provided by one or more fluid thermal switches (18) and a method for mitigating restart pinch during a hot restart. SOLUTION: The turbine power generating system includes a stator and a rotor (10) situated within the casing (12) of the stator. Auxiliary heat is provided to the stator casing during shutdown operations from a heat source via one or more fluid thermal switches (18) which are configured to provide localized heating to portions of the stator casing subject to restart pinch. The fluid thermal switch (18) includes two solid, thermal conductors (20, 22) having fluid contacting elements (26, 28) spatially separated within an insulated vessel (24). A highly conductive and capacitive fluid is provided to the insulated vessel (24) when localized heating is needed. COPYRIGHT: (C)2010,JPO&INPIT |
