T/P92 is being heralded as a superior and lower-cost alternative to T/P91 for new power plants with pressures above 3,600 psi and temperatures above 1,100F—such as the supercritical and ultra-supercritical units proposed to be built in the U.S. over the next few years. The switch from T/P91 to T/P92 would represent the next step in […]

Steve Elonka began chronicling the exploits of Marmaduke Surfaceblow—a six-foot-four, steel brush-mustached marine engineer with a foghorn voice—in the pages of POWER in 1948. That was the year that Marmy raised the wooden mast of the SS Asia Sun with the aid of two cobras and a case of Sandpaper Gin. This classic episode, written in the late 1960s, shows that even minor consequences of a steam turbine overhaul can cause problems. And as Marmaduke shows, solving any problem requires equal parts judgment, logic, and experience. Enjoy.

Both the states and the federal government are looking at who should decide which power plants are used at any given moment to meet demand. In question is which approach will reliably serve customers with the lowest-cost electricity. The Energy Policy Act of 2005 (EPAct) raised the issue when it directed the Federal Energy Regulatory […]

Futureproofing Gas Power Plants The Role of Gas is Changing—Fast The global energy transition is accelerating. As solar and wind expand and undercut fossil generation on cost, gas-fired plants are shifting from baseload to flexible, responsive assets. This shift demands new operational and investment strategies to stay competitive. Protect Performance. Extend Asset Life. The white […]

Discover how leading operators are maximizing asset value, reducing downtime, and avoiding unnecessary capital costs with advanced rotor life extension strategies. Your E- and F-class gas turbine rotors may be approaching OEM-defined end-of-life—but that doesn’t mean replacement is your only option. In this exclusive executive brief from Mechanical Dynamics & Analysis (MD&A), you’ll learn how […]

Tackling a Critical Turbine Performance Issue Gas turbine operators face constant pressure to maintain reliability while minimizing downtime and extending equipment life. One of the most significant operational challenges is exhaust gas temperature (EGT) spread—a key indicator of combustion balance and turbine health. Excessive EGT spread can trigger alarms or automatic shutdowns and significantly reduce […]

Designers of heat-recovery steam generators are using computational fluid dynamics software as one tool to reveal the invisible forces affecting the flow over, under, around, and through structures such as inlet ducts, distribution grids, and guide vanes.

A multitude of variables must be accounted for during the design and development of a wet-stack flue gas desulfurization system. The five-phase process detailed below has proven effective on more than 60 wet-stack system design studies. A basic understanding of these concepts will help inform early design decisions and produce a system amenable to wet operation.
