COURSE OVERVIEW:

Turbine auxiliary systems are the life-sustaining components of power generation and mechanical drive packages, ensuring that the primary rotating elements operate within safe thermal and frictional limits. This course provides a comprehensive technical breakdown of the lubrication, sealing, and cooling infrastructures that support high-speed steam and gas turbines. Participants will examine the interconnected nature of these subsystems and how a failure in a single auxiliary component can lead to a catastrophic trip of the entire turbine train.

The scope of this training encompasses the hydraulic principles of lube oil consoles, including the management of pressure-regulating valves, redundant pump configurations, and high-efficiency filtration units. We will investigate the critical role of seal oil systems in hydrogen-cooled generators and process compressors, focusing on the prevention of gas migration and the maintenance of differential pressure. The curriculum covers the chemistry and thermal dynamics of cooling water loops, ensuring that heat exchangers and oil coolers are optimized to handle the extreme heat rejection requirements of industrial turbines.

Coverage also includes the monitoring and instrumentation required to safeguard these systems, such as flow transmitters, temperature switches, and level controllers. By focusing on the maintenance of oil cleanliness and the prevention of varnish buildup, the course empowers operators to extend the life of bearings and seals. Through this detailed study, attendants will gain the expertise necessary to troubleshoot auxiliary system instabilities and implement proactive maintenance routines that guarantee the long-term reliability of the turbine package.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Identify all major components within a standard turbine lube oil and seal oil console.
2. Explain the flow path of lubricant from the reservoir through the bearing headers.
3. Manage the start-up and warm-up sequences for auxiliary oil pumps and emergency backups.
4. Analyze the function and calibration of differential pressure controllers in seal systems.
5. Evaluate the effectiveness of different oil cooling technologies, including plate and shell-and-tube.
6. Diagnose the causes of foam, aeration, and water contamination in turbine oil.
7. Implement rigorous oil sampling and analysis programs to monitor fluid degradation.
8. Oversee the maintenance of oil mist eliminators and reservoir venting systems.
9. Troubleshoot temperature fluctuations in the cooling water circuit during load changes.
10. Execute safe filter changeover procedures without inducing pressure spikes or trips.
11. Assess the impact of varnish on the operation of sensitive hydraulic control valves.
12. Coordinate the periodic testing of emergency DC oil pumps and battery systems.
13. Verify the integrity of seal oil traps and degasification tanks for hazardous service.

TARGET AUDIENCE:

This course is designed for Turbine Operators, Mechanical Maintenance Engineers, Plant Engineers, and Technicians responsible for the operation and upkeep of power plant or industrial turbine sets.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
