Turbine Efficiency, Part 2

3.0 1 Review SKU: HR01300CENDuration: 60 Minutes

This course is designed to explain how turbine efficiency and unit heat rate are affected by the use of attemperation, by the positioning of the turbine control valves, and by changes in extraction steam flows. After completing this course, participants should be able to explain why superheat and reheat attemperation cause heat rate to increase, and describe ways to prevent frictional losses in the turbine control valves. They should also be able to describe how heat rate is affected by changes in extraction steam flows.

Learning Objectives

  • Superheat and Reheat Attemperation
  • Describe how turbine efficiency and heat rate are affected by the use of superheat attemperators.
  • Describe how turbine efficiency and heat rate are affected by the use of reheat attemperators.
  • Turbine Control Valves
  • Describe how the positions of the turbine control valves affect turbine efficiency and heat rate.
  • Describe how frictional losses in turbine control valves can be minimized by shifting load between different operating units.
  • Describe how frictional losses in turbine control valves can be minimized by varying main steam pressure.
