Wednesday, May 22

8 a.m. – 4 p.m., General sessions (users only)

Timelines for the Tuesday afternoon and Wednesday user presentations and discussion sessions had not been finalized before CCJ went to press. However, the topics to be addressed include the following:

• Trip-reduction efforts in a 7FA fleet—including determination of focus areas, single-point vulnerability, and a case study on how some findings were addressed to improve reliability.
• 7F DLN 2.6+ combustor washer distress will provide a brief overview of the RCA for the existing washer and discuss the importance of replacing it with an upgrade.
• Combustion fallout because of inner-support-ring failures.
• Finding turbine-compartment leaks.
• Chemical foam cleaning of 7FA.03 compressors fouled with minerals.
• Compressor IGV adjustments to compensate for gas-turbine operational issues.
• Issues with a non-optical flame detection system.
• Design evolution and inspection quality control of first-stage buckets.
• HMI and controls enhancement.

When you receive your conference registration packet, be sure to look through the programs for Tuesday afternoon and Wednesday. There are sure to be more topics than those listed above; plus, you’ll have access to the final lineup of presentation times.

 

Thursday, May 23 (GE Day)

8 – 10:45 a.m., GE session (users and GE only)

Following the opening session there are four one-hour GE breakout sessions, each with three concurrent presentations. Here’s the lineup:

11 a.m., Breakout 1: Combustion turbine 101, Compressor and turbine, Digital solutions.

1 p.m., Breakout 2: CT auxiliaries, Power management, Supply-chain overview.

2:15 p.m., Breakout 3: Combustion, Running my plant to 2055 (part 1) Technical dialog (NCR, ER, TIL, RCA).

3:30 p.m., Breakout 4: 7F.04-200 upgrade, Running my plant to 2055 (part 2), Controls.

Here’s what each of the GE breakouts promises in terms of content:

• Digital solutions. How predictive ad prescriptive analytics are leveraged to optimize efficiency, reliability, and profitability.
• Combustion turbine 101. An introductory session covering power-generation and CT fundamentals, combustion theory, 7F evolution, Brayton cycle.
• Compressor and turbine. Latest field experience and best practices, emerging fleet issues, TIL revisions, new PSIB/PSSB releases.
• Power management. Getting comfortable with what’s happening outside the plant fence and thinking about ways to mitigate likely risks.
• Supply-chain overview. On-time delivery of parts, quality assurance, inventory, planning, etc. Rotors are a key topic in this session.
• CT auxiliary systems. Reliability improvements for auxiliaries, liquid-fuel and auxiliary upgrades, TIL revisions, emerging fleet issues.
