Instructors:
Daryll Turner and Keith Zanavich, Elliott Co./Ebara Group, Jeannette, PA
Target Audience:
This course is intended for individuals with limited knowledge of steam turbines who would like to gain a better understanding of these commonly applied equipment drivers. This course is intended for operators, maintenance mechanics, engineers, and supervisory personnel managing persons working with or on this equipment. The course will emphasize the practical aspects with limited theory and will address steam turbine fundamentals. Individuals attending will leave with an understanding of:
- Basic steam turbine principles
- Steam turbine components and function
- How the components are assembled and work together
- How to operate steam turbines
- Steam turbine safety issues
Description:
The intent of this course is to provide individuals with a working knowledge of steam turbines. The course will cover basic steam turbine thermodynamics, turbine design considerations, applications, common turbine specification documents, control methods, turbine components, internal component alignment, and operating the different types of steam turbines.
Individuals completing this course will leave with a practical understanding of steam turbines, how they are constructed, how they function, and how they should be operated. This will provide a firm foundation for operating, monitoring, troubleshooting, and maintaining steam turbines.
