Combustion Dynamics in Gas Turbine Power Plants Workshop

Date: Monday, September 8, 2008
Time: 8:30 a.m. - 5:00 p.m.
Cost: $500.00*

Instructor
Tim Lieuwen, Associate Professor, Georgia Institute of Technology

Who Should Attend
Attendees can have a broad range of educational experience, from high school diploma to a Ph.D. degree in engineering, or with some practical background and hands-on experience. Plant Technicians, Maintenance Engineers and Engineer/Supervisor, including Engineering VP's, people (internal or external) to power plants, whose functions/tasks relate directly or indirectly to gas turbine operability and reliability issues and those responsible for procuring combustion dynamics monitoring systems will benefit from attending this workshop.

Course Overview and Objective
This one-day course introduces students to combustion dynamics. It begins with an overview of development and field experience with combustion instabilities, and will describe case studies from several DLN combustors development efforts. It then provides background on what causes dynamics and what parameters (e.g., fuel composition and temperature) influence it. Next, it discusses strategies for treating dynamics problems by combustor tuning. Finally, it discusses dynamics monitoring approaches, and various issues associated with using dynamics monitoring for machine protection and health monitoring.

Course Highlights

• Field experience with combustion dynamics
• Combustion instability mechanisms
• Control/abatement approaches
• Instrumentation for dynamics monitoring
• Combustor protection and health monitoring strategies using dynamics data

Basic Gas Turbine Metallurgy and Component Repair Workshop

Date: Monday, September 8, 2008
Time: 8:30 a.m. - 5:00 p.m.
Cost: $500.00*

Instructors
Lloyd Cooke, Director, Operations, Liburdi Turbine Services; Warren Miglietti, Senior Engineer, GE Power Systems; Doug Nagy, Industrial Component Repair Manager, Liburdi Turbine Services

Who Should Attend
Gas Turbine operating companies, GT repair shop personnel, GT OEM designers and technical staff, insurance companies, typically technical staff, engineers and technicians responsible for some aspects of gas turbines - design, upgrade, repair, analysis, operations, maintenance

Course Overview and Objective
This workshop will explain super-alloy materials, component damage experienced from service exposure, techniques used to analyze the remaining life of components removed from service, protective coatings, component repair technologies, and quality assurance of repairs. The workshop includes many case study examples and the last section is devoted to a workshop where attendees develop component repair solutions. Participants may submit questions in advance regarding repair issues faced in their jobs.

Course Highlights

• The seminar provides answers to common questions and issues for engine support staff
• What makes super-alloys especially suited for gas turbine components
• How do the different damage mechanisms affect the component - oxidation, corrosion,. erosion
• How are high cycle fatigue, low cycle fatigue damage caused, prevented, and repaired
• What are the various heat treatments used in repairs, and why are they important
• What are the advantages, disadvantages of the many types of protective coatings
• What are the critical quality control steps in component repair
• How can you reliably extend the service life of these valuable components
