Understanding the Steam Turbine Start-Up Process

A steam turbine’s start-up involves multiple stages, each impacting its performance and operational lifespan. A 300 MW steam turbine follows a structured process:

• Impulse Start Parameters: Ensuring optimal steam temperature and pressure.
• Warm-Up Phase: Gradual increase in rotor speed to prevent material stress.
• Grid Connection: Attaining synchronization with the power grid under controlled load conditions.

Key Findings from the Research

The study emphasizes:

• Mathematical Modeling: A model was developed to optimize start-up time while maintaining stress levels within safe limits.
• Thermal Stress Analysis: Evaluations using finite element analysis (FEA) to determine rotor stress distribution.
• Cold Start Optimization: Identification of factors affecting stress and efficiency during cold starts.
