COURSE OVERVIEW:

The integration of gas and steam turbines is the cornerstone of modern power generation and heavy industrial mechanical drives. This course provides an exhaustive exploration of the thermodynamic cycles that govern these machines, specifically the Brayton cycle for gas turbines and the Rankine cycle for steam turbines. Participants will analyze the mechanical architecture of both technologies, focusing on how high-velocity fluids are converted into rotational energy through sophisticated blade profiles and nozzle arrangements.

The scope of the training encompasses the critical auxiliary systems that ensure turbine longevity and reliability. We will cover the complexities of high-pressure lubrication systems, hydraulic governing, and the intricate sealing mechanisms required to prevent fluid leakage. The curriculum bridges the gap between theoretical efficiency and practical operation, detailing how ambient conditions, fuel quality, and steam purity directly impact the output and structural health of the turbine components.

Maintenance strategies addressed in this course transition from reactive to proactive, emphasizing the importance of borescope inspections and vibration signature analysis. Attendees will study the degradation mechanisms specific to each turbine type, such as hot corrosion in gas turbines and erosion or scaling in steam turbines. By the end of the program, participants will be equipped to manage major overhauls, interpret performance trends, and execute precision maintenance tasks that extend the mean time between failures.

COURSE OBJECTIVES:

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

1. Distinguish between impulse and reaction turbine designs and their specific applications.
2. Evaluate the efficiency of the combined cycle power plant (CCPP) configuration.
3. Interpret turbine performance curves and maps under varying load conditions.
4. Manage startup and shutdown thermal ramping to minimize rotor stress.
5. Identify the primary causes of blade fatigue and creep in high-temperature sections.
6. Troubleshoot hydraulic governor response and speed control instability.
7. Execute precise alignment and balancing procedures for multi-stage rotors.
8. Monitor lube oil chemistry to prevent oxidation and bearing failure.
9. Analyze vibration data to detect misalignment, unbalance, or loose components.
10. Implement effective turbine washing procedures (on-line and off-line).
11. Coordinate the maintenance of steam condensers and vacuum systems.
12. Assess the integrity of labyrinth seals and carbon ring packing.
13. Perform detailed borescope inspections to identify internal hardware damage.

TARGET AUDIENCE:

Mechanical Engineers, Turbine Operators, Maintenance Supervisors, Reliability Engineers, and Technical Personnel responsible for power plant or mechanical drive operations.

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.
