Phosphate Hideout

This phenomenon is called phosphate hideout and it can result in changes of pH, as well as the concentrations of phosphate and other chemical species in the boiler water. Hideout usually first occurs in boiler tubes with the highest heat flux and low mass flow, where departure from nucleate boiling (DNB) or under deposit concentration occur.
