The ASME Research and Technology Committee on Water and Steam in Thermal Power Systems is in the
process of producing a document which itemizes and outlines key issues that require addressing to ensure a successful and timely commissioning of a combined cycle power plant. The generic best practical practices will be described in such a manner that the reader can link the concepts to pre-design considerations (i.e. minimization of component failures, long-term maintenance and operating costs) to ensure reliability. The paper will outline the document framework, progress to date, future needs, and will present a field example.

KEYWORDS: combined cycle, heat recovery steam generator (HRSG), cleaning, passivation, corrosion, pretreatment, water quality, steam purity, chemical treatment programs, cycle chemistry control, monitoring, lay-up, component failures.
