Stop compressor debris at the source with field-applied HVTS

Advanced GTs / By

“Stop debris at its source, not after it forms,” cautions Eric Duvekot, VP of Engineering at Integrated Global Services (IGS), as he explains how field-applied high-velocity thermal spray (HVTS) addresses oxide flaking in the hot, high-pressure compressor sections of advanced-class gas turbines, and outlines proof points from OEM testing and fleet experience (Fig 1). The […]

Applying FFS in power cycles: Benefits, risks, and best practices

HRSGs / By

Film forming substances (FFS), including film forming amines (FFA) and other proprietary non-amine based FFS, are increasingly used in steam and HRSG cycles to reduce corrosion during operation and, especially, during shutdown and layup. In a January 27, 2026, CCJ-hosted webinar, the IAPWS Power Cycle Chemistry (PCC) committee explained what current guidance supports, why results

CONTROLS: Cooldown procedure options for legacy frames

7EA Users Group, Controls, Frame 6 / By

Legacy Turbine Forum, No. 7 in a series By Luke Williams, PE, Consultant www.geLegacyGasTurbineSupport.com IN THE BEGINNING Engineers who joined the GE gas turbine department in the early days often came from steam turbine design, where cooldown procedures were essential to prevent rotor thermal bow, a condition that can lead to vibration on startup. Several

Taking the noise out of turbine monitoring

501 F&G Users Group, 7EA Users Group, 7F Users Group, Advanced GTs, Aeros, D5-D5A Users, Frame 6 / By

High-temperature pressure sensors and accelerometers rarely get much attention when they are doing their jobs. But when a combustion dynamics channel goes noisy, a cable loosens, or a monitoring system starts throwing spikes, the consequences can move quickly from nuisance to risk. That was the practical takeaway from Dave Martin, business development manager at PCB

Extending the life of legacy gas turbine fleets

7EA Users Group, Alstom Owners Group, Frame 6 / By

Globally coordinated, locally delivered reconditioning supports aging legacy units With mature gas turbine fleets, operators are under increasing pressure to maintain performance, reliability, and availability beyond original design life. Reconditioning has become a critical tool for extending asset life, restoring efficiency, and reducing lifecycle costs while managing outage risk. GE Vernova supports legacy fleets (GT8,
