TG308W – (W) Steam Turbine: Starting, Loading, & Shutdown

TG308W – (W) Steam Turbine: Starting, Loading, & Shutdown

2 days - 14 PDH Credits Awarded



The intent of this course is to enhance the participants understanding of Steam Turbine Starting, Loading and Shutdown Instructions (or procedures). These instructions and their interpretation have a direct impact upon the unit life-span, starting, and shut-down times.  The goal is to optimize the starting conditions and minimize the time required for a turbine roll-up.  It is our experience, not to be critical, but, all too often the startup procedures utilized in the plant have lost focus.  Knowledge is the key.  Personnel need to understand “why” and the better they understand the “why” the better they may implement procedures. The course emphasizes why and how steam turbine parts are damaged; interpretation of the OEM recommendations; and what an operator can do (or cannot do) to optimize the start-up situation.  A topical outline includes:  Review of Steam Turbine Fundamentals, Use of TSI, Thermal Stress, Starting and Loading Instructions, Abnormal Events. This course is recommended for Control Room Operators, Shift Supervisors, Operations Superintendents, and Engineers. The course specifically targets Wsteam turbines.


Upon completion of this course the participant will be able to:
  1. Describe thermal stress; how it is derived and what is the impact upon steam turbine components.
  2. Describe how personnel can minimize the negative impact of thermal stress while minimizing start-up times.
  3. Describe the importance of the Fracture Appearance Transition Temperature.
  4. Describe those Turbine Supervisory Instruments typically found to support starting and loading decision making.
  5. Demonstrate the ability to interpret the OEM starting and loading instructions.
  6. Demonstrate the knowledge necessary to apply the OEM starting and loading instructions to his/her application.
  7. Demonstrate an understanding of causes, indications, and required actions for common abnormal steam turbine operational events.

Course Outline

  1. Review of Steam Turbine Fundamentals: Energy Transfer, Theory of Operation, Turbine Components
  2. Turbine Supervisory Instruments important to Starting & Loading Instructions: Eccentricity, Shell (Casing) Expansion, Differential Expansion, Rotor Expansion, Metal Temperatures
  3. Thermal Stress: Definition, Tensile versus Compressive, Temperature Differentials, Cyclic Duty
  4. Starting Instructions: Drains, Temperature Mismatch, Acceleration, Speed Holds, Synchronizing, Loading, Unloading (Normal), Unloading (Emergency)
  5. Abnormal Conditions: Excessive time off turning gear, vibration incidents (evaluation and action), rotor long, rotor short, water induction awareness, excessive temperature/pressures, loss of vacuum.
