9F-Class Combustion Systems1. 8K- Original design of 9F-class combustion system- In use on AO 1-6, 8000 factored hours repair interval

2. 8K(2) (8K version 2)- Improved design, very slight changes to 8K hardware- In use on AO 1-7, 8000 factored hours repair interval

3. 24K-EL- Mechanical design differences, use of Super ‘B’ TBC and HVOF coating- CSA-only, currently 16000 factored hours repair interval pending validation

4. 12K- Only 9FA at Akzo Delesto has this design- Described at later date, not in this presentation
