Finding the best place to sample heat recovery steam generator (HRSG) tubes isn’t as hard as finding a needle in a haystack (but it’s like that). Ask most HRSG users where they take their routine tube samples for monitoring under-deposit corrosion in the high-pressure evaporator, and they’ll tell you, “first row, because it’s the hottest […]

Drawing on decades of gas turbine experience, GE’s Power Services business announced on May 16 that it is expanding its cross-fleet service offerings to a broader portion of the F-class market, including Siemens’ SGT6-5000F and SGT-800 models, and Mitsubishi Hitachi Power Systems’ (MHPS’s) 501F technology. “GE is proven as one of the technology leaders and […]

Those responsible for the operation or maintenance of thermal plant boilers know there is nothing trivial about hopper ash buildup. At a minimum, plugging can lead to decreased output, unscheduled maintenance

Malware-based attacks against utilities and power plants are increasing six-fold according to a recent federal report. Power plants have become an appealing target because of a lack of detection and monitoring

As water demand soars in every corner of the world amid widespread drought and water scarcity concerns, recovery and recycling of wastewater is increasingly becoming a valuable solution to alleviate pressures

A sharp surge in new, larger offshore wind installations in Europe throughout 2017 dramatically shows the viability of a technology that has truly come of age. As costs fall and generation capacity increases

According to the Occupational Safety and Health Administration, 22 million people—including nearly all power plant workers—are exposed to potentially damaging noise at work each year in the U.S. Hearing

Waypoint Leasing, a global firm that claims to be the world’s largest independent helicopter leasing company, has identified offshore wind farms as a growth opportunity for the helicopter market. Although still a small market, offshore wind power is expected to grow in coming years. According to WindEurope, a Brussels, Belgium-based wind industry advocacy group, a […]

Tennessee Valley Authority (TVA) CEO Bill Johnson in an exclusive interview with POWER suggested that the power industry continues to face an uncertain future.  Johnson said that during his 40-year career, he has seen more change in the last five years than in the previous 35 combined.

Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of steam turbine blades and other internal components is one of the most serious problems experienced in power plants. The problems often reduce plant availability by limiting generation […]
