HRSGs

With the 2024 HRSG Forum fast approaching in June, have a look at the breadth of topics and discussion points covered at last year’s event during the solutions provider presentations, featured here, and all the other components of the conference. The 2023 HRSG Forum event in Atlanta, the organization’s first physical meeting since the Covid […]

Editor’s note: During the main-session presentations at HRSG Forum 2023, Duke Energy and Structural Integrity Associates Inc (SI) jointly presented on an online “HRSG damage monitoring system,” which is highlighted in CCJ’s summary report of that conference. At the same Forum last June, Jacob Boyd presented “Wireless high-energy-piping monitoring program,” recently implemented at his plant,

By Vaughn Watson, Vector Systems Inc Connect with Vaughn on LinkedIn The efficiency and long-term performance of an SCR system is largely dependent on several key design considerations for its various components. When complex NOₓ reductions on heat-recovery steam generators (HRSGs) are required, there are critical aspects of the system that must be addressed to

It was developed in the late 1970s, with the focus of its use in the nuclear power industry. The material is part of the Creep Strength Enhanced Ferritic (CSEF) steels group,

Steven C Stultz, Consulting Editor Barry Dooley, Structural Integrity Associates (UK), opened the Cycle Chemistry Workshop on Day One of the HRSG Forum’s 2023 Conference and Vendor Fair, June 12 – 15, at the Renaissance Atlanta Waverly, with Film-forming substances for combined-cycle/HRSG plants: History, background, and needs. He first presented IAPWS nomenclature background for film-forming

Steven C Stultz, Consulting Editor The afternoon workshop on Day One of the HRSG Forum’s 2023 Conference and Vendor Fair, June 12 – 15, at the Renaissance Atlanta Waverly, focused on welding and metallurgy. It was a combined effort among Jeff Henry and Kevin Hayes, Applied Thermal Coatings, and Amy Sieben, Industrial Air Flow Dynamics

There are several reasons stacks don’t get much attention from operators on their rounds—among them: They’re static and there’s nothing much to see externally except perhaps peeling paint. Forgetting the switchyard, they’re likely a longer walk from the control room base than any other plant component. Internal access is not possible with the plant in

By Vaughn Watson, Vector Systems Inc The performance of an SCR system depends on the robustness and efficiency of the sum of its parts. The flow-distribution devices placed into the exhaust stream are no exception. Each of the critical parts of the system must be designed and built to effectively provide the proper distribution and

The headline should not surprise any reader of the COMBINED CYCLE Journal. It’s a “given.” The challenge is how to maximize the saving at the least cost. Until relatively recently, the widely preferred method for cleaning tubes in heat-recovery steam generators serving cogeneration and combined-cycle plants was dry-ice blasting. It effectively dislodges iron oxides, ammonia
