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
