Power Generator Operation & Maintenance
The Power Plant Operations training series addresses the need of the power plant worker to understand basic and advanced principles of power generation and the safe, efficient operation and maintenance of the power plant itself. It also provides a foundation for learning more of the technical aspects of power plant operations and maintenance.
This course also introduces waste-to-energy energy conversion, including fuel, furnace design, and plant operations.
Upon successful completion of this course, the delegates will be able to:
