Real-time optimization pushes out into distribution networks

Optimization of the utility production and delivery system at the University of Texas, Austin (UT-Austin) is the poster child for a work in progress. After all, you don’t optimize a 90-year-old powerplant, one with a mix of really old boilers and state-of-the-art gas turbine/HRSGs overnight or even in a few years. It’s also a glimpse […]

Doosan takes a high-profile position in aftermarket services

In today’s topsy-turvy world of electric-power generation and delivery anything can happen, and it does. Recall that only a couple of years ago, the OEM with the largest position in the generation sector purchased a major competitor and tried to take by storm the industry’s aftermarket business—worldwide. That might have led some to conclude that

Increase intervals between gas-turbine fuel-valve overhauls with water cooling

Reliable operation of dual-fuel gas turbines on oil demands that owner/operators protect against coking of distillate in fuel-system components. Active cooling is one solution available to users for assuring both reliable starts on liquid fuel and reliable fuel transfers from gas to oil. Recall that stagnant fuel in supply lines not protected against heat radiated

Advanced manufacturing center enables Conval to better serve HRSG users 

HP superheater and reheater drain-system designs and operating practices that do not remove all condensate prior to initiation of steam flow during cold, warm, and hot startups are unable to protect tube-to-header connections, header bores, and nozzle-to-header connections from severe thermal fatigue damage. Such damage has resulted in many premature tube failures and can be
