521-02 - Combustion Air and Flue Gas Flow Paths and Components
Learning objectives
- Describe the individual flow paths of primary and secondary air
- Compare the relative temperatures of the reheat and superheat boiler sections
- Explain the use of forced and induced draft fans
- Describe the function of the following flue gas system components: air preheaters, scrubbers, and expansion joints
Course overview
The previous lesson in this series introduced the design and function of the combustion air and flue gas systems. The Combustion Air and Flue Gas Flow Path and Components training course builds on that knowledge and focuses on the individual flow paths and their elements. It highlights how their efficient operation relates to overall plant performance.
This online training course traces the flow paths of typical power plant combustion air and flue gas systems. It describes how major components within these paths operate. This course covers:
- Forced draft (FD) fans
- Air preheaters
- Wind box/primary and secondary air
- Boiler components
- Dust collection/particulate recovery components
- Scrubber components
- Induced draft (ID) fan
- Flue gas stack
This course is part of the Combustion Air and Flue Gas System training series.
