PURPOSE:To ensure overflow by providing a piping from respective overflow devices of an oil tank for a main turbine and an oil tank for driving a water supply pump to an oil cleaner and providing a float valve at each oil cleaner inlet. CONSTITUTION:A system from an oil tank 1 for a main turbine to an oil cleaner 10 is separated from one from an oil tank 11 for a water supply pump turbine to the oil cleaner 10 and float valves 23, 24 are provided at respective oil cleaner inlets. Thus, even if flow balance between oil exhaust pipes 7, 17 is disordered during stoppage of the main turbine, overflow from the oil tanks 1, 11 is ensured by setting the float valves respectively to the running requirements of the turbine. |
