Covers the operation and maintenance of high- and low-pressure boilers and their related auxiliaries. Includes elements required to safely operate, service, and maintain boiler and auxiliary equipment pertaining to state-of-the-art cogeneration and heating and power plants. Learners are required to interface with actual or virtual plants as part of the activities for this course. May require plant visits as part of course work.

- Process and generating plant boilers: watertube, central station, process
- Boiler construction, details, boiler design considerations
- Boiler fittings, accessories, and appliances
- Boiler operation and maintenance procedures
- Boiler emissions control, boiler efficiency improvement
- Fuels, combustion, gas-oil-solid fuel burning
- Boiler controls -- positioning, metering, control loops/measurement
- Boiler auxiliaries -- pumps, water treatment
