Extraction condesing turbine

                                                                     

        The ENK and EHNK type turbine are multi-stage extraction condensing turbine and are designed on building-block system and their passage-flow part is optimized. The ENK and EHNK type turbine increase one stage or two stage controlled extraction on the NK and HNK foundation.

        ENK--maximum inlet steam conditions: 10MPa/480℃ maximum extraction pressure: 4.5MPa

        EHNK--maximum inlet steam conditions: 14Pa/540℃ maximum extraction pressure: 4.5MPa

        A governing system of unit consists of many standard assemblies. The governing system automatically changes the extraction pressure to a quantity of electrical or a pneumatic quantity, then the electrical or pneumatic governor achieves work. This unit also provides the protection devices that have difference functions.
