CT522 - (ABB Series GT8, 11, 13 & 24/26) Combustion Turbine O&M

4 days - 2.6 Continuing Education Units Awarded

Improve unit availability and reliability with a quality understanding of operations and maintenance of a modern ABB combustion turbine. Series GT8, 11, 13, and 24/26 are included. Reliable operations of modern ABB equipment depends upon operators being thoroughly knowledgeable on what is required for proper preparation, start-up and shutdown as well as correct interpretation of alarms and recommended responses.

This course has been designed for plant personnel who are involved in safely and effectively operating and maintaining combustion turbine produced by ABB. Specifically the course targets Control Room Operators, Shift Supervisors, Engineers, Maintenance Supervisors, and Superintendents.

OBJECTIVES
Upon successful completion of this course the participant should be able to:

1. Describe the major components and systems associated with combustion turbine.
2. Describe the sequencing that occurs in a normal startup, synchronization and operation.
3. Describe the different fuel systems and requirements for operation.
4. Describe the standard routine operational maintenance philosophy for:
   1. Combustion Turbine Auxiliaries
   2. Thermal Block
   3. Compressor
5. Demonstrate the ability to use effective and safe maintenance procedures.
6. Properly plan the maintenance outage prior to shutdown.
7. Demonstrate the knowledge necessary to measure and interpret information as it relates to the unit outage.
8. Demonstrate the knowledge necessary to disassemble/reassemble equipment in an orderly and safe manner.
9. Demonstrate the knowledge necessary to properly clean and inspect turbine components.
10. Describe combustion turbine control concepts and protective features.
