S21 Turbo Generator Set

Dare:2018-11-23 15:02:00 Clicks:

S21 turbine is multi-stage condensing turbine. It adopts a double velocity stage (or single velocity stage) and seven to nine pressure stages at the steam path. As a module turbine, its actual stages used depend on the output power, rated rotate speed, inlet steam pressure and temperature. It has the optimized design to guarantee high efficient output rated power of the turbine. 

The rotate speed of the turbine is 3000r/min with output power range 3000-6000KW. The regulation system adopts full hydraulic regulator or electro-hydraulic regulating mode (WOODWARD 505 controller + CPC ii electro-hydraulic converter or domestic DEH electro-hydraulic regulation system) with multi-valve nozzle governing and double layer arrangement. S21 turbine is multi-stage condensing turbine which can not only drive large rotate equipment (variable speed running) like fan and compressor as driving condensing turbine, but also drive generators (constant speed running) as condensing turbine for power generation. The turbine can fit a wide range of purposes and occasions.
