  • Alternative Energy Blog: Heat Recovery Steam Generator Purge Credit Success

    At the 2019 Ovation Users’ Group Conference , a U.S. power producer shared their story about shrinking down to a 17-minute purge on their combustion turbine (CT) startup. A heat recovery steam generator (HRSG) purge removes combustible levels of fuel mixtures prior to startup. A purge credit allows credit for a prior purge for the next startup with a normal shutdown occurs or modified fuel systems for both CT and duct…

  • Alternative Energy Blog: Early Detection of Heat Recovery Steam Generator Tube Leaks

    A NACE International paper, HRSG Tube Failures: Prediction, Diagnosis and Corrective Actions highlights the challenge of these failures: Many HRSGs were originally designed for base load operation. Recent economic factors have led to drastically increased cycling of many units. This has exacerbated the rate of failures. These leaks can lead to forced outages that create associated costs including fines, lost time…

  • Alternative Energy Blog: Prevent Valve Delamination in Conventional Power Plants

    Author: Paolo Tomaini Conventional power plants are being disrupted by an increasing demand for renewable energy. The priority in providing energy to the grid associated with the intermittent intrinsic nature of the renewable energy output is creating a shift from base-load power down to cycling in traditional plants and causing failures. The demand for renewables is only expected to grow over the next few decades…

  • Alternative Energy Blog: What Digital Transformation Could Mean for a Combined Cycle Plant

    Author: Douglas Morris The growth of renewables and distributed energy resources are challenging the traditional economic models of the utility industry. A growing school of thought in power generation is that embracing some form of digital transformation could very well provide an avenue for better economics. The problem is, though, that digital transformation has been ill defined and the focus is on “the technology…
