Multiple Upgrades Improve Reliability of a D-11
Wednesday, December 9, 2020 @ 3:00pm EST/12:00pm PST
EthosEnergy recently completed the first major inspection of a D-11 type steam turbine in combined cycle service. This unit is part of a 1,240 MW gas fired four-on-two combined cycle plant which entered commercial operation in August 2011. This presentation covers the technical details of the complete project, including the upgraded SMART Seal design and N2 packing head horizontal joint bolting upgrade, the 40” titanium L-0 blade weld repair, as well as challenges and lessons learned from the outage.
Key Takeaways for Users
- Early preparation for major overhaul is key for success
- Titanium L-0 blade repair is a cost-effective alternative to blade replacement
- Shortcomings in N2 packing box joint design can be addressed pre-outage
- N2 joint upgrade should be completed in combination with SMART Seal upgrade
- EthosEnergy can provide the complete package including open and close, engineered solutions, parts and repairs
