QUESTIONS AND ANSWERS Phosphate Hideout

2011-1-31 · Phosphate hideout is a phenom-enon that causes boiler water control difficulties. It is defined as the disappearance, by precipita-tion or absorption, of the ionic phosphate (PO 4) species, in the boiler water under high heat transfer or high load conditions. When the high heat flux or high load condition is reduced, the species (phosphate

Boiler water can permeate the porous deposit resulting in localize corrosion. When it is coupled with significant heat flux, concentration of the boiler water occurs rapidly speeding the corrosion. The corrosion action is a result of the formation of caustic-ferritic compounds through the dissolving of the protective magnetite film.
