TBC DURABILITY, PART I: Effect of hydrogen combustion on thermal barrier coatings

7F Users Group, Advanced GTs, Best Practices / By

Decarbonization of the electric power industry will increase the use of hydrogen as a gas-turbine (GT) fuel—alone or in combination with natural gas. Issues for hot-section components when burning hydrogen include the following: increased flame speed, temperature, quenching distance, steam in combustion products (from 12% to 21%), and loading. The resulting increase in erosion and […]

PROCESS DIAGNOSTICS: Software-as-a-service diagnostics underscores whole-of-plant approach

Advanced GTs, Best Practices, HRSGs / By

Metroscope, a relatively new entrant (2023 launch) to the US real-time powerplant process diagnostic software market, recently conducted a webinar to build more awareness of its technology and to differentiate it from other packages (some of which have been evolving since the early 1990s and can be considered “standard” in combined-cycle plants and in centralized

BOILER VALVES: Avoid Stellite delamination with alternative hardfacing

Advanced GTs, Best Practices, HRSGs, STUG / By

By Richard Laukam, ValvTechnologies LLC Steam stop valves, located at the boiler outlet, provide isolation. These typically are wedge-type gate valves, stop-check valves, or parallel-slide gate valves. Hardfacing often is applied to the seat and closing member (wedge, plug, or discs) to reduce wear and extend the duration of leak-free service. Hardfacing is the building

HRSG need not be a limiting factor in GT upgrade

Advanced GTs, Best Practices, HRSGs / By

By Vignesh Bala, Vogt Power Editor’s note: This is the second of three articles exploring the impacts of gas-turbine upgrades on heat-recovery steam generators. It focuses on “re-rating” of the HRSG after the upgrade to extract maximum benefit from the work. Part 1, which examined the driving factors behind GT upgrades, appeared in August. Part

GTEN 2023 SYMPOSIUM: Realities of hydrogen come under close scrutiny

Best Practices / By

The 2023 symposium of the Gas Turbine Energy Network (GTEN), held in October 2023 in Banff, Canada, and reviewed earlier in the year (CCJ No. 77, p 96), included many presentations on hydrogen, proposed as a key fuel for a “net-zero world,” when no additional carbon is being discharged to the atmosphere. GTEN focused on
