Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.

Continuous-Blowdown Block Valve Reduces Startup Time
At Essential Power LLC’s Newington Energy Facility, the high-pressure (HP) steam-drum continuous blowdown system was designed to cascade flow to the intermediate-pressure (IP) steam drum. While the valve worked well for controlling flow, it did not have the degree of leak-tightness required for stopping flow from the drum during typical overnight shutdowns. An automatic full-port ball valve was installed upstream from the existing automatic control valve to eliminate the risk of flashing.

Eliminate Leakage by Drain, Vent, Block Valves
Select your valves carefully. Be sure metal seats are available when service temperatures are 400F and above, stems are blowout-proof, seat leakage meets the tightest specs after installation, coatings assure long life, and can be accessed internally, inline, for inspection and maintenance.

Water-Cooled Check Valves Boost Reliability of 7FA Liquid Fuel System
Owners/operators of dual-fuel gas turbines often experience coking problems with standard liquid-fuel check valves. After switching from oil to gas, the oil remaining in check valves, which are located close to the combustors, is exposed to high temperature. Water-cooled check valves for the liquid-fuel circuit can help to alleviate the problem.

Converting from Hydraulic to All-Electric Gas Control Valves Benefits Frame 6 Owners
Young & Franklin valves have been in use on Frame 6 gas turbines for a decade. One advantage of an all-electric control valve is that it eliminates varnish issues by eliminating the control oil required by hydraulic actuators. Plus, electric valves are more responsive than hydraulically operated valves, have greater range, are easier to maintain, and enhance plant safety.

Inspect Steam Valves for Stellite Delamination
Stellite liberation from large valves installed in high-pressure (HP) and hot reheat (HRH) steam systems serving F-class combined cycles has emerged as an important industry concern. EPRI has established a committee on “Cracking and Disbonding of Hardfacing Alloys in Combined-Cycle Plant Valves” to dig into the details. The work, funded by several sponsors, began early this year. John Shingledecker (jshingledecker@epri.com), the technical manager for this program, said the project timeline is estimated at 14 months.

How to Reduce Catalyst Lifecycle Cost, Improve Reliability
Balancing the requirements of each SCR system in the fleet can be challenging. A system can reduce NOx by greater than 95%, but when the efficiency of the SCR is pushed beyond 85% and—or, if—the outlet emissions are less than 5 ppm, the system becomes much more sensitive to several independent system parameters. These include overall catalytic potential, effective ammonia injection/mixing in the flue-gas stream, flue-gas characteristics for inlet NOx, velocity, and temperature distributions.
