Impulse Turbine
                   Reaction Turbine
 


(N0.75 N1.5 N3 N6 N12 Type)

       The condensing turbine is single casing, single shaft, impulse type, when the powers not exceed 3000kW, turbine will provide a reduction gearbox; the powers exceed 6000kW, turbine will connect with a generator directly.

       For northern high cold zone of china, turbine may apply to the heating in winter through supplying the low vacuum circulating water(generate electricity in summer), so that to advance the economy benefit of power station (middle and smaller type).

       The non-controlled extraction condensing steam turbine may provide a certain steam flow for industrial need.

       This series unit consists of a rotor and stator. The rotor is assembled. The stator includes a casing, nozzle and diaphragm, labyrinth gland and bearing etc. A governing valve is connected with an actuator of speed regulation system via a mechanical lever.

       The turbine uses a full hydraulic governing system and provides the protection devices that have difference functions.
