Product Description
Core Principle
High-speed steam turbines operate by:
- Steam Energy Conversion: High-pressure steam from a boiler passes through nozzles, converting thermal energy to kinetic energy (high-velocity flow).
- Impulse/Reaction Mechanism:
- Impulse Turbines: Steam strikes curved blades, transferring momentum to spin the rotor.
- Reaction Turbines: Steam expands through alternating fixed (stators) and rotating (rotors) blades, generating reactive force for rotation.
- Multi-Stage Design: Stages (high/intermediate/low pressure) gradually extract energy, maintaining high speed via stepwise steam expansion.
Key Design for High Speed
- Compact Rotor: Small diameter reduces centrifugal stress.
- High-Strength Materials: Alloys (e.g., nickel-based) withstand thermal and mechanical loads.
- Aerodynamic Blades: Optimized profiles minimize drag and enhance flow efficiency.
- Advanced Bearings: Hydrodynamic lubrication systems reduce friction for sustained high RPM.
Applications
- Aero-derivative power plants, industrial compressors/pumps, micro-turbines for CHP systems, and high-power-density generators.
Advantages
- High Power Density: Compact design delivers more power per unit volume.
- Efficiency: Multi-stage expansion maximizes energy extraction from steam.
- Fast Response: Rapid acceleration suits dynamic load requirements.
- Direct Drive: Ideal for high-speed machinery (e.g., compressors, generators) without gearboxes.
- Material Optimization: High-strength alloys enable reliable operation at extreme RPM.
- Space Savings: Reduced footprint compared to low-speed counterparts.
YTS's Technical Advantages
1. The multi-stage impulse steam turbine has 2 to 4 more pressure stages than that of other manufacturers. The stage distance is reduced to allocate more stages in the flow part, the enthalpy drop of each stage is reduced. The diameter of flow structure is reduced, thus the blade height loss is significantly reduced. This technology was selected and listed in 2019 National Recommended Catalogue, Guideline and Cases of Industrial Energy-Saving Technologies and Equipments, released by Chinese Ministry of Industry and Information Technology.
2. Monolithic forged rotor assembly adopts whole forging method and it's a rigid rotor. The integration of the impeller and the shaft increases the safety and stability of operation. The blade profile is optimized and the partition is synchronously matched.
3. Reduce the rotor diameter and increase the blade length, compress various contact gaps to reduce steam leakage and make the steam act to the maximum extent, thereby to achieve high efficiency and more electricity generation under the same working conditions.
4. Add a sleeve cylinder, usually in casting or forging type, reinforced with a partition sleeve, and works with the newly added pressure stage and partition to increase the working air tightness of the new pressure stage, reduce air leakage and enhance operation safety, thus improve the working capacity of the unit;
5. Increase the length and quantity of comb-teeth steam seal from original 36 teeth to 45 teeth, and the tooth height is also increased, which effectively reduces steam leakage;
6. Comparing with similar steam extraction back pressure units from domestic market, it can improve efficiency by 10% to 30%, reduce the unit dimension and occupy less space at the same time. The optimization of the flow structure enables the unit to produce more power under the same working conditions, thus generate energy-saving economic benefits.
