The multi-stage backpressure 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.
NG--maximum inlet steam conditions: 10MPa/480℃ maximum exhaust pressure: 2MPa
HNG--maximum inlet steam conditions: 14Pa/540℃ maximum exhaust pressure: 2MPa
HG--maximum inlet steam conditions: 14Pa/540℃ maximum exhaust pressure: 4.5MPa
The turbine is axial flow, single shaft, reaction type, and has a reduction gearbox, when front section dimension exceed 50, turbine will connect with a generator directly.
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. The balance piston is provided on the rotor.
The stator includes a outer casing(consists of a front section, middle section and exhaust section), steam chest(for NG and HNG type)or integral inner casing(for HG type) , 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 electric-hydraulic type, it consists of many standard assemblies; it provides the protection devices that have difference functions under the user requirements.
The excellence of backpressure turbine is to take a high internal efficiency.
