HRSGs

Many combined-cycle units originally designed for baseload operation are now required to cycle frequently, with still more starts and more rapid ramping over a wider range when in automatic generation control (AGC) mode. As a result, a significant number of heat recovery steam generator (HRSG) failures experienced worldwide have been at least partly attributed to […]

The HRSG Forum with Bob Anderson contributes significantly to industry knowledge on the design, operation, and maintenance of heat-recovery steam generators with its lineup of technical presentations by subject matter experts, plus hands-on discussions among owner/operators, component and service providers, and concerned OEMs. In sum, this premier event encourages the exchange of experience and specifics

The experiences shared at the Australasian HRSG Users Group (AHUG) annual meeting have been chronicled for the last decade by CCJ ONsite and in the print edition of the Combined Cycle Journal. Beginning here, and going forward, you’ll also benefit from the lessons learned/best practices of fired-boiler owner/operators facing technical and operational issues closely related

Technical presentations by subject matter experts on topics of importance to owner/operators of combined-cycle and cogeneration plants powered by gas turbines are the foundation of the HRSG Forum with Bob Anderson. Consulting Editor Steve Stultz has abstracted the presentations below from the group’s fourth annual meeting. O&M personnel likely will find at least one or

INTRODUCTION This two-part report summarizes information on cycle chemistry and thermal transients at combined-cycle/HRSG plants shared at the industry’s leading technical forums worldwide over the last several years—such as the US-based HRSG Forum with Bob Anderson. The foundation for many presentations and discussion sessions on these subjects comes from assessments undertaken in the last decade

A valuable feature of Power Users conferences is audience polling, which was pioneered by the 7F Users Group a few years ago. The steering committee and presenters use polling to ask owner/operators for their opinions on industry trends, the information needs of attendees, etc. Because the feedback is virtually instantaneous, it can identify where clarification

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

Editor’s note: The traditional annual conferences of all user groups serving the gas-turbine sector of the US electric-power industry scheduled between Mar 1, 2020 and Dec 31 have been canceled because of the Covid-19 pandemic. The 30th anniversary meeting of the Western Turbine Users (slated for March 29 to April 1 at the Long Beach

Special to CCJ ONsite By Larry Muzio and Sean Bogseth, Fossil Energy Research Corp, and Frederic Vitse, GE Power Portfolio Selective catalytic reduction (SCR) is widely used to reduce NOx emissions from gas-turbine powerplants—both simple- and combined-cycle units. Once the catalyst is installed it is important to monitor its activity periodically. This involves removing a

So you switch hemispheres in both directions, west to east then north to south, and you discover that the pesky HRSG operational issues and concerns you are familiar with are much the same everywhere. The 2018 Australasian Boiler and HRSG Users Group (ABHUG) Conference and Workshops, held last November, confirmed this view. The organization’s 11th
