Pump health audit sharpens outage planning

Planned work outages are an exercise in efficiency and preparation. As global power demand continues to increase, plant operators are compelled to execute required maintenance within increasingly shorter outage windows. The pressure on already stretched labor resources and the strict O&M budgets compounds the challenge of outage planning. Getting better information on equipment health offers […]

Exhaust liner failures: Why small defects turn into forced outages

Ask Scott Schreeg of SVI Bremco what turns a manageable exhaust-liner repair into a forced outage and the answer gets specific fast: a failed stud weld, a loosened sheet, or a hotspot hidden behind the liner system. None looks catastrophic at first glance. But once exhaust flow starts working behind the liner, the problem can

Proactive turbine-oil maintenance moves to the front line of reliability

A turbine end user could once treat lube-oil management as background maintenance. That is no longer a safe assumption. During a recent CCJ webinar offered by C.C. Jensen on proactive turbine-oil maintenance and varnish control, presenter Eddie Rowland, joined by former GE Vernova engineer Tom Freeman and Duke Energy lead engineering technologist Steve Malec, made

Maximizing the lifespan of CO catalyst: What operators should check before ordering replacement

For many gas-turbine users, CO-catalyst trouble shows up first as a compliance headache: stack CO starts climbing at low load, differential pressure changes, and the plant is forced to decide whether it is looking at a cleaning issue, a system issue, or end-of-life catalyst. That decision now carries more economic weight than it did a

Taking the noise out of turbine monitoring

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

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
