At Combined Cycle Power Plants the Heat Recovery Steam Generator (HRSG) is an easily-overlooked, but key component, providing steam to the steam turbine and to attached process steam hosts. While base-loaded HRSGs tend to be the most reliable - cycled or two-shifted plants suffering from accelerated damage - the importance of allocating sufficient resources to maintenance of the HRSG is often only realised in hindsight.
Tetra Engineering will have a booth next month at the upcoming PowerGen Middle East in Abu Dhabi on October 12-14. We will present our latest service offerings including Field Services, Engineering Analysis, 3rd Party Engineering, and Training. Come see us at the N21 booth, and enter your business card for your chance to win a Wilesco Steam Engine Generator!
At the 2014 ASME Power Conference in Baltimore, David Moelling of Tetra Engineering presented the recent research paper titled: Role of Boiling Mode and Rate in Formation of Waterside Deposits in Heat Recovery Steam Generator Evaporator Tubes, written by David Moelling and James Malloy. The paper discusses results from research in the theory of boiling mode and deposit formation, employing advanced thermal simulation of evaporation in real boiler models, and compares results with actual experiences in recent years.
Since 2007 the ASME B31.1 Power Piping Code has included Chapter VII, establishing mandatory requirements for Operation and Maintenance. The key elements of this program are discussed here, and require that Operators outline a detailed maintenance plan for their Covered Piping Systems (CPSs). The Code also requires that operators perform regular Condition Assessments of their CPS ensuring that relevant degradation mechanisms are being covered.
