Steam Turbine Generator:

SteamTurbine:

Technology for steam turbine used in power plant has become mature, and Runh is capable of supplying different models of steam turbines, like condensing, air-cooled, heat supply, back pressure ones.

The ultra supercritical steam turbines, supercritical steam turbines, subcritical steam turbine, air-cooled steam turbine, air-cooled heat supply steam turbine of different capacities ranging from 60-1000mw are all available in Runh.

Generator:

1. Generator of all capacites
2. Performance tested
3.Quality guaranteed

Generators of all models and capacities can be supplied by Runh Power plant, such as brushless excitation generator, static excitation and coaxial DC excitation generator. All our generators adopt the technology of Alstom. In order to gurantee the quality of the products and satisfy the generator's overall performance and detection, we do the overall performance test in the large-scale generator laboratory according to the standard requirements. The generators can be adopted to meet different requirements and demands of the customer.

QF air-cooled turbo-generator, one of its typical models, is mature and well-approved, with the capacity ranging from 1.5MW to 30MW according to customers’ requirements.

The stator consists of frame, core and winding, which are all of excellent quality. For generators over 12MW, transposition bars are reduced to extra loss. Air-cooled rotors are made of cast alloy steel, and adopt copper wedges on both ends, which are made of duralumin. Retaining rings on both ends are made of Mn18Cr5. Open-air cooling system and closed circulation cooling systems are adopted in the QF generator. Brushless excitation and static silicon excitation are designed in the air-cooled turbo-generators. Advanced inspecting instruments are adopted to supervise manufacturing process, which can satisfy new products developing and technology research demand. Professional generator test station guarantee the overall performance test of generators when they leave the factory.

Overall quality management network is established so as to ensure the quality of the generator. The generator can be used in District heating power station, combined heat and power generation, Exhaust-heat power plant, Mine-mouth electric power plant, Garbage power station and Steam gas combined cycle power station.
