Unit Start-up and Shutdown Training

561-01 Preparing for Power Plant Start-ups

When you complete this lesson, you will be able to describe the basic checks that must be performed on plant equipment, including the boiler, turbine, and generator, prior to a power plant start-up.

  • Recognize the role an electrical dispatcher plays in preparing for a power plant start-up
  • Recall the purpose of determining appropriate ramp rates for starting up the boiler and turbine
  • List the four basic categories of pre-start checks on each of the following:
    • Boiler
    • Steam turbine
    • Generator

561-02 Power Plant Start-up Procedures

When you complete this lesson, you will be able to describe the basic concepts and typical tasks associated with putting a fossil fuel-fired power plant online.

  • Describe the basic steps associated with the following tasks:
    • Filling the condensate/feedwater system
    • Firing a steam boiler
    • Rolling a steam turbine
    • Synchronizing a generator to the electrical grid
    • Increasing load
  • Explain the purpose of turbine preheating

561-03 Preparing for Power Plant Shutdowns

When you complete this lesson, you will be able to describe the basic tasks that must be performed on plant equipment prior to a power plant shutdown.

  • List and define the three classifications of power plant shutdowns
  • Discuss the purpose of blowing soot and removing ash from the boiler
  • Discuss coal system preparations completed prior to a scheduled shutdown
  • Explain what four conditions must simultaneously exist while reducing the firing rate on a boiler
  • Describe each of the basic tasks associated with ramping-down a turbine/generator

561-04 Power Plant Shutdown Procedures

When you complete this lesson, you will be able to describe the basic steps associated with taking a fossil fuel fired power plant off-line. In addition, you will be able to explain how operators prepare a power plant for an annual outage.

  • Describe the common sequence of steps to remove a pulverizer from service for an extended period of time
  • Describe the basic steps followed to take each of the following out of service:
    • Scrubber
    • Steam turbine
    • Generator
  • Explain how a power plant is prepared for an annual outage
