What you'll learn

  • Calculate turbine efficiency using two methods
  • Identify factors affecting turbine efficiency
  • Explain control valve impact on turbine efficiency
Course Description

 This lesson explains how to calculate turbine efficiency and describes how parameters, components, and problems can affect turbine efficiency. • Explain the two methods of calculating turbine efficiency • Describe how each of the following affects turbine efficiency: – Chemical deposits and internal erosion – Internal and external seal leakage – Variations in steam temperature and pressure – Backpressure – Attemperation spray flow – Extraction steam flow • Explain how control valves can be the source of a loss that is typically attributed to the turbine
