The condensing turbines are designed on building-block system and their passage-flow part is optimized, turbine consists of three main sections, each section has some dimensions.

        NK--maximum inlet steam conditions: 10MPa/480℃

        HNK--maximum inlet steam conditions: 14Pa/540℃

        The turbine is a single casing, a shaft, reaction type, and has a reduction gearbox, when front section dimension exceed 50, turbine will connect with a generator directly.

        This series unit is designed on the turbine parameters (called standard type) specified by GB(National Standard of PRC ), also turbine is designed in accordance with the user’s special requirements(called non-standard 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 integral rotor. A governing stage is impulse blade and pressure state blades in the drum rotor are reaction blade cascade, end stages blades are twisted blade with the fork type blade root. The balance piston is provided on the rotor. The stator includes an outer casing(consists of a front section, middle section and exhaust section), steam chest, guide blade support ring, labyrinth gland and bearing etc. A governing valve is connected with an actuator of speed regulation system via a mechanical lever.

        A governing system is full hydraulic and consists of many standard assemblies; it provides the protection devices that have difference functions under the user requirements.
