The compressor session that launched the user portion of the 2019 501F meeting touched on several topics of interest to the group, including the following: Complications with the re-installation of outlet guide vanes (OGV) surprised many attendees. The OEM installed the airfoils backwards, something most plant personnel didn’t think was possible. A clue that something

Depending on your plant’s power purchase agreement, adding peak-firing capability to simple- and/or combined-cycle gas turbines can provide significant economic benefit—provided the peak-fire capability is used strategically at times of high demand to avoid unnecessary maintenance. Recall that traditional peak firing increases the firing temperature a fixed, incremental amount above the rated baseload value. This

Tuxpan, home to two 501F-powered 2 × 1 combined cycles operated by NAES Corp in Mexico, is located in a salt air environment containing a great deal of dust from both agricultural and industrial activities in the area. These contaminants present a challenge because plant performance rapidly degrades as the air inlet filters foul. Quarterly,

Costly fogging-pump failures and consequent maintenance repairs had negatively affected Fremont Energy Center’s summer peak season performance and its maintenance budget. Plant personnel realized the need to prevent premature pump failures and avert costly fogging-system downtime. The plant maintenance staff began investigation of multiple issues linked to premature failures of the station’s fogging pumps. In

TransCanada, Klamath Energy’s fuel-gas supplier, installed its control, filtering, and metering station at the plant fence. The piping network on plant property, serving the gas turbines, auxiliary boiler, and plant heaters, was buried, and expensive to inspect. Buried gas lines serving the facility’s 501F-powered 2 × 1 combined cycle had to be inspected every five

The strategy allowed a supplier of invisible “pieces and parts” to be brand-recognized by the end user. Emerson’s Power & Water Solutions business might consider “Ovation at your side.” At its annual Ovation Users Group conference, the Emerson

The 501F Users Group Vendorama program gives attendees access to live presentations by dozens of products/services providers offering O&M solutions. The program matrix for the 2019 meeting allowed each attendee to participate in up to seven presentations, vetted for technical content by the organization’s Board of Directors. There were seven sessions, each featuring five concurrent

The Gas Turbine Association (GTA) salutes Congressmen Paul Tonko (D-NY) and David McKinley (R-WV), and Senators Lisa Murkowski (R-AK), Thom Tillis (R-NC), Richard Burr (R-NC), and Joe Manchin (D-WV), for the time and effort they and their respective staffs contributed to advancing the Energy Act of 2020. GTA Chairman Jonathan Li noted, “GTA appreciates the

Regardless of where you fall on the 3Hs of the H2 economy—hype, hope, happening soon—everyone can appreciate a seminar which delivered information on actual experience. The webinar, “Hydrogen: Utilizing Combustion Turbines as a Solution to ‘Low to No-Carbon’ Initiatives,” was presented by PSM (Power Systems Mfg LLC). After a quick review of global-climate headlines, Jeff
