Specific HRSG configurations impose equally specific requirements for water and steam chemistry. The operating chemistry limits in this document are meant to provide a starting point from which each plant can develop its own plant-specific limits. Lower pressure HRSGs that provide process steam have very different requirements from high-pressure HRSGs that drive steam turbines for power generation. Selection of appropriate plant chemistry limits is greatly influenced by the presence of those pieces of equipment that are particularly sensitive to deposits and corrosion, the first and foremost being the steam turbine.
