One of the unique aspects of the 7F Users Group’s 2020 Digital Conference is the opportunity to interact online with the OEM and nearly 50 third-party solutions providers. Ten companies in the latter group were selected by the steering committee to conduct live technical presentations which are available for on-demand playpack. The remaining solutions providers participated in the conference with virtual booths in the Vendor Fair conducted Tuesday and Wednesday of Week One. They connected directly with users via video (or audio) links.

In case you missed the opportunity to visit with one or more of these companies at the Vendor Fair, the editors have compiled brief summaries of the products/services they showcased, along with links to that information. The names of experts to contact for details are included, in addition to a variety of downloadable case studies, white papers, etc.

JASC Controls

Pitfalls to avoid for enhanced liquid-fuel-system reliability (users only)

Schuyler McElrath, one of the electric-power industry’s leading experts on liquid fuel systems for gas turbines, has new product development as one of his responsibilities at JASC Controls. His presentation simplifies the complexity inherent in liquid fuel systems and focuses on what design features owner/operators should be aware of to assure reliable starts on oil, reliable transfers from gas to oil, and vice versa, and reliable operation on both fuels. McElrath stresses that while some issues can be addressed with hardware upgrades, system infrastructure changes are an equally important part of the performance improvement process.  

ARNOLD Group

Advanced steam-turbine-casing warming for startup (users only)

ARNOLD is perhaps best known globally for the insulation systems it provides for all types/designs of gas and steam turbines. Outside North America it is equally well known for its onsite turbine machining services. Turbine warming systems have matured as product line in the last several years given the need for gas and steam turbines to start faster to satisfy grid requirements.

Pierre Ansmann, the company’s global head of marketing, Norman Gagnon, ARNOLD’s North American project manager, and controls expert Joris Ringelberg provide users a primer on turbine warming systems. Their presentation covers the following:

• • Maintenance and operational benefits for individual customers.

  • Differences between various warming-system arrangements.

  • Durability and reliability.

  • The importance of proper insulation for a warming system.

  • Warming-system controls.

  • Cost and duration of initial installation and periodic maintenance.

GT upgrades: Low-load impact on HRSGs (users only)

Anand Gopa Kumar, who leads HRST’s Analysis Dept, provides users critical insights on how increasing the turndown capability of their gas turbines to provide the operational flexibility required in many areas of the country today may impact the HRSG. He identifies areas within the boiler at risk of exceeding their design capabilities and possibly susceptible to long-term damage. Kumar also suggests modifications to the HRSG and associated equipment (including attemperators, internal liners, superheater tubes, steam separators, etc) to enable the desired turndown with minimal risk.
