CT518 – (Siemens V84.2) Combustion Turbine Generator Maintenance

4.5 days - 32 PDH Credits Awarded

$2,995.00

Description

This 4.5 day course was developed to improve the effectiveness of maintenance activities associated with Siemens V84.2 combustion turbine-generators.  First we need to learn to properly identify all the major components and systems.  An overview of the identification of this equipment is offered in advance of the more detailed lectures to follow.   Next, we need to learn to better plan and implement gas turbine maintenance outages.  Planning, safety, procedures and considerations regarding replace/reuse/repair decision-making are very important topics covered.  We examine the most common causes of gas path damage and the impact upon efficiency, reliability and availability.  Related topics include clearance data taking, NDE, bearing inspections, and alignment issues.  Combustion turbine operation is discussed from the perspective of auxiliary systems and how operating factors may impact maintenance intervals.  Combustion, hot gas path and major inspections are discussed.  The generator is included as well.  Specific discussions include the identification of the major generator components, disassembly, and inspection. A topical outline includes: Review of CT Fundamentals; V84.2 Construction and Operating Principles; Auxiliary Systems: Maintenance Preparation and Planning; Combustion Section Inspection; Turbine Inspection; Major Inspection[ Generator Components, Disassembly, & Inspection; and Alignment. This course has been specifically designed for plant personnel who are involved in safely and the maintaining of these Siemens V84.2 combustion turbine-generators.
