Here in China 3 units of of Used of second hand 10500kW/10.5kV/50HZ Wartsila power plant (total running time 25000hr) in on floating on auction.
Plant Specification
Type of plant
The power plant has been designed for base load application, intended for parallel operation with public supply system. The power generation part consists of a gen-set using a Wartsila VASA 12V46 diesel engine as a prime mover driving the generator generating the electrical power.
The operation of the diesel generating set is carried out from the control room. The operation method is manual with automatic synchronizing, based on the operator’s push-button order. Auxiliary equipment are controlled from panels mounted close to the equipment.
The equipment includes control equipment, meters and sensors ended for the operator to monitor the equipment and processes, to give alarm in case of abnormal conditions; to stop the diesel power plant operation in case of hazardous conditions occurs.
The diesel power plant is designed for heavy fuel oil operation.
The main systems of the power plant are:
Electrical system
Fuel system
Lubricating oil system
Compressed air system
Cooling water system
Charge air & exhaust gas system
Steam system
The total electrical power output is generated by three diesel generating set of the type Wartsila Vasa 12V46 at 500 rpm with the following electrical characteristics:
Generator nominal output 13137kVA (cosø=0.8)

Max. wet bulb temp. 32�?BR>Max. water temp. to charge air cooler 40�?BR>The layout drawing for 3x10500kW power plant attached.
Main technical data for 3x10500kW/10500V HFO generator
The gen-set consists of a Wartsila VASA 12V46 diesel engine and an ABB HSG1600K12 self-cooled three phase A.C. generator. The engine is mounted on rubber elements on a fixing rail bolted to the foundation, thus achieving a good vibration reduction.
The flexible coupling ensures that the generator and the engine do not affect each other due to small deviations in alignment, temperature movements or dynamic free forces. All external piping systems are connected to the engine via flexible connections listed in the respective auxiliary systems.
Main data for diesel engine
The gen-set is using a Wartsila VASA 12V46B diesel engine as a prime mover to drive the generator. The Wartsila Vasa 12V46B is a four stroke, direct injected, turbocharged and intercooled design.
