Stop compressor debris at the source with field-applied HVTS

“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 scottschwieger

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

Easy as 1,2,3: Choose inlet filters based on GT-specific standards

ISO has published the first turbomachinery-specific standards for air intake filters. ISO 29461-1, ISO 29461-2 and ISO 29461-3 establish uniform test methods for efficiency and dust holding capacity, performance in fog and mist, and mechanical integrity at high pressure. While this is not breaking news, the combination of the three standards is a powerful decision-making

HIGH-ENERGY PIPING: High-temperature tees present growing risk in HEP systems

Advanced GTs, CCUG, HRSGs, STUG / By scottschwieger

High-temperature tees in main steam and hot-reheat service are emerging as a serious integrity risk across combined-cycle and advanced coal-fired plants. Speaking at the NBBI 93rd General Meeting, Dr. John Siefert (EPRI) reported hundreds of field leaks attributed to creep-related cracking in wrought tees, with damage appearing in as little as 37,000 operating hours (Fig

501F Users Group: OEM, OOEM, vendor session recaps (2025)

501 F&G Users Group / By scottschwieger

What would a gas-turbine user-group meeting be without extensive participation from equipment manufacturers and solutions providers? The 501F and 501G conferences continue to demonstrate why this blend matters. User-only sessions, covered in detail here, focus on fleet experiences, common pain points, and lessons learned shared directly by owner/operators. But the meeting’s broader value emerges when
