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
