Critical HRSG On-Line Water/Steam Monitoring Parameters

摘要

Combined-cycle power plants continue to be the primary replacement for the many coal-fired plants that have been or soon will be retired. Like their coal boiler predecessors, combined-cycle heat recovery steam generators (HRSGs) operate at high pressures and temperatures. Proper chemistry control and monitoring are critical to prevent corrosion and fouling upsets that may range from relatively minor to catastrophic.
