Power plants built 20 years ago weren't optimized to achieve the operational goals of today and physics and financial challenges of the near-future. So, how can we prepare?
See how GE Gas Power is helping to build a world that works.
Older steam turbines can be unreliable and require frequent repairs or component replacements. Even without major operational problems, a unit with high service hours is at risk as it reaches the end of its design life. Advanced steam path (ASP) can solve many maintenance and lifetime problems.
A cost-effective alternative to a complete section replacement in cases where HP/IP shell condition is not a concern, GE’s advanced steam path (ASP) upgrade delivers up to a 2% increase in steam turbine output (in the same bottoming cycle) through the recovery of aging losses and improved technology.
The typical post-upgrade regular maintenance interval is 100,000 hours, which is very likely to be longer than the original design, thus saving costs and increasing availability.
The ASP “Lite” upgrade addresses multiple TILs with a solution that includes improved materials, blade profiles, and advanced sealing for improved thermal efficiency. The new steam path provides improved reliability, availability, and thermal efficiency for increased MW output, and reduced plant heat rate.
Protect your steam turbine’s main stop and control valves (MSCVs) and combined reheat valves (CRVs) by coupling hardware upgrades with advanced health-monitoring analytics.
With the logistics necessary to maintain reliable supply chains, coordinate resources, and comply with regional regulations, GE is well positioned to deliver outage services—including repairs, testing, onsite services, and stocking programs—where and when you need them.
