Chemical feed should be continuous. Chemical pumping rates can create problems especially for neat feed set ups. Using on/off feed systems such as a recycle timer can create problems. Chemical feed pumps should be sized or product strengths should be adjusted to allow continuous feed.
Oxygen scavengers are best fed to the storage section of the deaerator or feedwater tank. In most low-pressure industrial boiler systems, if oxygen remains in the feedwater and enters the boiler, it is too late to remove all of the oxygen and protect the boiler and condensate from oxygen corrosion. A residual of sulfite or other.
Oxygen scavenger in the boiler cannot chemically reduce all of the oxygen before it escapes with the steam or reacts with the metal surfaces.
Chelant Treatment
EDTA dosage requirements and variations will be similar to phosphate in that there is a reaction and residual portion to the dosage calculation:
(Feedwater hardness) x (3.8) % active / 100 + ppm EDTA desired residual / (feedwater cycles) x % active / 100 = ppm EDTA Product
Sodium Hexametaphosphate supplier
Sodium hexametaphosphate is a commonly used source of orthophosphate anion used to precipitate calcium in low-pressure boilers. With dispersants the calcium phosphate becomes a fluidized sludge capable of being blown down and out of the boiler before the calcium can form a deposit.
Example
The reaction rate is the first part of the equation and the residual the second part:
[ (0.72 x Ca + 1.08 x PO4/ Feedwater Cycles) ]
= ppm of 100% sodium hexametaphosphate in feedwater.
The dosage of sodium sulfite or other oxygen scavengers may be calculated by looking at their reaction rate to remove the oxygen and then their residual dosage to provide a feedwater or boiler water residual.
Sodium Sulfite Example
The reaction rate is:
2Na2SO3 (7.88 ppm) + O2 ( 1 ppm) → 2Na2SO4
For the residual, 1.6 ppm Na2SO3 will yield 1 ppm SO3.
The total calculation equation to remove residual oxygen and provide a boiler water residual is:

Don't forget to wear eye protection when working with Silver Nitrate. NEVER get Silver Nitrate powder or solutions into your eyes.
Don't forget to wear Hand gloves. Before initiating Do not contact your skin with Silver Nitrate solutions. If you do, the moment you go into sunlight, the exposed skin will turn black.
This unsightly, but generally harmless color will last for about 10 days. There is no way to get it off, once it has turned black.
Preventing Silver Nitrate stains on your skin
