Abstract
A method for determining the existence of phosphate hideout in a steam generating steam cycle (10) so that the nature of the impact of the phosphate hideout on pH and the PO.sub.4 concentration in the boilerwater of the steam generating steam cycle (10) can be ascertained. The subject method includes the steps of determining from the concentration of PO.sub.4 that is provided to the steam generating steam cycle (10) the input of PO.sub.4 to the steam generating steam cycle (10), determining the loss of PO.sub.4 from the steam generating steam cycle (10) that is attributable to blowdown and contamination and solubility, and thereafter determining as a result of subtracting from the input of PO.sub.4 to the steam generating steam cycle (10) the loss of PO.sub.4 from the steam generating steam cycle (10) whether there exists phosphate hideout and, if so, what the magnitude of the phosphate hideout is as well as what impact the phosphate hideout will have on the pH of and the PO.sub.4 concentration in the boilerwater of the steam generating steam cycle.
