Boiler Operation & Control: Boiler Feedwater & Steam is part three of the Boiler Operation & Control five-part training series.
The course teaches students the multiple ways to control boiler water and boiler water chemistry. In addition, students will be exposed to the three basic approaches to feedwater control.
Course objectives include:
- Explain why feedwater must be treated before it enters a boiler
- Explain how chemical treatment is used to inhibit scale and corrosion in a boiler
- Explain how to minimize impurities in boiler water and why shrink and swell occur
- Identify components and their functions in a single-element feedwater control system, a two-element control system, and a three-element control system
- Describe how a three-element control cascaded feedwater control system differs from other means of controlling drum level.
