Advanced steam path (ASP) solutions
Regardless of your industry, GE can help release the potential of your steam turbines. We’ll help improve efficiency, operational flexibility, reliability, and output—either of individual parts or whole systems.
Benefits
The right retrofits
Because of their conservative configuration, many industrial steam turbines have capacity and capabilities that may be underutilized. These solutions can be installed simply and without impact to timeline during your next outage.
The latest upgrades
Whether your industrial steam turbine operates in chemical manufacturing, metals, marine/transportation, a refinery, or in pulp and paper many older units experience performance losses because of changes in nozzle and bucket throat areas and blade profiles, as well as deterioration and increased clearances.
By rebuilding the turbine with modern high efficiency components (usually nozzles, buckets, valves, and seals), our efficiency upgrade addresses the degradation, leading to improved efficiency and reliability for industrial turbines.
Advanced steam path (ASP) solutions
Upgrades and retrofits can give your steam turbine a new lease on life, boost reliability and efficiency, and even reduce CO2 emissions by replacing parts with improved components. GE offers full or partial steam path upgrades to ensure tailored, fast, and cost-effective solutions depending on customer needs and applications. Our upgrades can address the common factors holding back the industrial use of steam turbine power generation efficiency, parts obsolescence, performance deterioration, and decreased reliability.
Moreover, when changed operating conditions lead to different output requirements—or in the case of poor efficiency or when the risk of age-related failure is on the rise, GE offers solutions ranging from partial steam turbine retrofits (inner cylinder and partial blading replacement) to full retrofits (completely new steam path).
ASP industrial turbine upgrade and retrofit benefits:
- Reduced maintenance costs while increasing turbine availability
- Rapid installation during a major overhaul
- Industrial steam turbine efficiency improvements and turbine capacity
- Steam turbine life extensions
- Scope can be expanded to include other plant equipment and adapted to changed plant boundary conditions
