Maintenance for G.E. Heavy Duty Gas Turbines
Disassembly Inspections
Combustion Inspection (CI)
- Concentrates on the combustion liners, transition pieces, and fuel nozzles
- Crossfire tubes, retainers, spark plug assemblies, flame detectors, combustion covers, and flow sleeves are the other key hardware.
- Recommended inspection for MS6B Hours / starts is 12000 / 800
Hot Gas Path Inspection ( HGPI )
- Full scope of combustion inspection, in addition, a detailed inspection of the turbine nozzles, stationary stator shrouds, and turbine buckets
- IGVs, bushings, and compressor blading are the other key hardware.
- Recommended inspection for MS6B Hours / starts is 24000 / 1200
Major Inspection ( MI )
- Examine all of the internal rotating and stationary components from the inlet of the machine through the exhaust section of the machine
- Recommended inspection for MS6B Hours / starts is 48000 / 2400
Running Inspection
- Full scope of speed, load, fired starts, fired hours, startup time, coast down time, and vibration data
Concentrates on
- Temperatures of inlet ambient, turbine exhaust, turbine Wheelspace, lube oil header, lube oil tank, exhaust spread, and bearing drains
- Pressures of compressor discharge, lube pump, cooling water, fuel, bearing header, and filters
- Generator of output voltage, Bars, loads, field current, field voltage, vibration, stator temperature, and phase current
