STEAM TURBINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603682 titled 'STEAM TURBINE
The abstract describes a steam turbine with a unique stator vane design that improves efficiency and performance.
- The steam turbine includes a first rotor blade and a stator vane positioned downstream in the axial direction.
- The stator vane features an airfoil portion, a tip-side wall surface, and a hub-side wall surface.
- The tip-side wall surface is angled towards the central axis of the rotor on the downstream side, enhancing airflow and energy conversion.
- This design optimizes the flow of steam through the turbine, increasing power generation efficiency.
Potential Applications: - Power generation plants - Industrial processes requiring steam turbines - Renewable energy systems
Problems Solved: - Improved energy conversion efficiency - Enhanced turbine performance - Reduced energy losses in steam turbines
Benefits: - Increased power generation capacity - Lower operational costs - Enhanced overall system efficiency
Commercial Applications: "Optimized Stator Vane Design for Steam Turbines: Improving Efficiency and Performance in Power Generation"
Questions about the technology: 1. How does the unique stator vane design impact the overall efficiency of the steam turbine? 2. What specific advantages does the angled tip-side wall surface of the stator vane provide in terms of energy conversion efficiency?
Original Abstract Submitted
A steam turbine according to at least one embodiment of the present disclosure, includes: a first rotor blade disposed in an outer periphery of a rotor; and a stator vane adjacent to the first rotor blade on a downstream side in an axial direction of the rotor. The stator vane has a stator vane airfoil portion, a tip-side wall surface located on a tip side of the stator vane airfoil portion, and a hub-side wall surface located on a hub side of the stator vane airfoil portion. The tip-side wall surface is inclined to approach a central axis of the rotor toward the downstream side in the axial direction.
