Main Functions and Characteristics of Turbine Stators

Guide Airflow

The turbine stator guides high-speed airflow along a predetermined path through its specialized geometry and flow channel design. This optimization of airflow characteristics enhances energy conversion efficiency.

Convert Kinetic Energy

As high-speed airflow passes through the turbine stator, the curved shape and flow channel design of the stator surface convert the kinetic energy of the airflow into static pressure energy. This conversion increases gas pressure, improving turbine performance.

Reduce Airflow Speed

The flow channel design of the turbine stator reduces the speed of the airflow, minimizing turbulence losses as the airflow exits the turbine. This reduction in speed enhances the overall efficiency of the turbine.

Adjust Flow

By modifying the geometry and flow channel design of the turbine stator, the flow and speed of the airflow can be precisely controlled. This adjustability allows for the optimization of turbine performance under varying operating conditions.

Heat-Resistant Materials

Turbine stators are typically manufactured from high-temperature alloys or other heat-resistant materials, ensuring stability and durability in high-temperature, high-pressure environments. These materials provide exceptional thermal resistance, mechanical strength, and corrosion resistance.
