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

A great many combined cycle plants were built in the nineties and early 2000s. Not so long ago, many considered them to be reaching their end of life. But the recent power plant construction boom has convinced many asset owners to keep these units running. Some are upgrading them to ensure they last another twenty

More than 500 registrants from 56 countries signed up for the March 31 IAPWS/CCJ webinar on damage and failure in the phase transition zone of steam turbines. That turnout said plenty before the first slide appeared. The subject was narrow by title, but not by consequence. Deposits, pitting, corrosion fatigue, stress-corrosion cracking, steam purity, carryover,

By Christopher Schroeder and Daniel Michels, Vogt Power International Preface The ability to operate combined cycle power plants to efficiently meet a variety of power demands continues to drive change within the power industry. Combustion turbines (CTs) are central to this flexibility, with low load operation providing greater operating range. Heat Recovery Steam Generators (HRSGs)

Water-cooled stator windings have been in commercial service since the early 1960s and remain common on large machines, generally those above about 400 MW. Dr. Robert Svoboda, speaking in the May 26 IAPWS Power Cycle Chemistry webinar on generator cooling-water chemistry, put the installed base at roughly 2000 water-cooled stators outside Russia and China, about

As the power industry evolves to meet growing demands for reliability, flexibility, and decarbonization, the success of any power plant depends on one constant: the expertise of the people who operate and maintain it. While advanced technology drives the energy transition, it is a skilled workforce that keeps critical assets running safely and efficiently. At

Legacy Turbine Forum, No. 8 in a series By Luke Williams, PE, Consultant www.geLegacyGasTurbineSupport.com Theme and scope More gas-turbine users may soon face the problem that landed on one Northeast plant’s desk: available fuel-gas pressure was going down, but the operating obligation was not. The supplier said line pressure would be reduced from 320 psig

The 12th IAPWS European HRSG Forum, EHF2026, met May 19-21 at Monash University in Prato, Italy, with Barry Dooley of Structural Integrity, UK, and Bob Anderson of Competitive Power Resources, USA, serving as co-chairs. The forum remains one of the more concentrated technical exchanges for combined-cycle users, suppliers, consultants, and HRSG specialists because it stays

A life built on reliability Clyde V. Maughan died Feb. 7, 2026, at age 99, leaving behind the sort of record the power industry rarely sees and never forgets. He earned a BS in electrical engineering from the University of Idaho in 1950, joined General Electric in Schenectady that same year, spent 36 years with
