Monitoring cycle water chemistry in fossil plants. Volume 1, Monitoring results: Final report

EPRI report CS-4629, published in 1986, contains operating cycle chemistry guidelines to assist utilities in reducing water and steam contamination and resulting corrosion, scaling, and deposition. These guidelines were based on consensus opinion utilizing information then available and were not validated through actual plant testing. The objectives of this project are: to monitor the major parameters of cycle chemistry in a range of fossil-fired plants; to compare the monitored parameters with the interim guidelines. The project team designed and constructed state-of-the-art instrumentation and data acquisition systems to measure and record continuously the chemical parameters specified in the interim consensus guidelines (ICG). The team then installed and operated these systems at four utility power plants. Nine international organizations conducted parallel monitoring efforts on 29 generating units. An industrial fossil plant group of 14 utilities and boiler and turbine manufacturers reviewed the monitoring results from each of the plants as did the participating international organizations. 137 figs., 43 tabs.
