Sodium Nitrate in Steam Boilers

Doug Oest

Hello Wallies. Need some help again.

Does anyone use Sodium Nitrite to treat steam boiler water(after they have been cleaned) for tube/metal protection?

If so, have you ever experienced foaming or a bouncing water line from the use of such a chemical?

Any help would be appreciated.

Thanks

sodium phosphate

years ago bell and gossett had some stuff on useing trisodium phosphate, (the phosphate that was removed from laundry soaps as well as comet all purpose cleaner) also known as a paint brush cleaner, and general all purpose pre-painting cleaner, used in HW Htg. systems as a PH modifier to assure the flux or other residue was "adjusted" to the "basic" side of PH world rather then allowing the water to get acidic or become acidic after years of neglect... I know youve never heard of anyone not checking their boiler water annually, i liken it to why do you change or check the oil in your car, when you dont believe in haveing
your heating equipment checked annually, its about priorities i guess. anyway check archives from bell and gossett on the sodium phosphate advice.. When i was in buisness and bought it from a paint wholesealer concentrated,20lb bag, (be careful it is hygroscopic and caustic)... (not hardware variety) i used a half a cup in most residential systems then checked with PH paper after a day or so...
good luck

sodium nitrite

a lot of low pressure steam boiler treatments use sodium nitrite and sometime sodium molybdate, slowly work the treatment levels up to recomended dosage if surging occours use bottom blowdown to clear up, for more information try checking Nu Calgons website

I've been wondering about water treatment for steam boilers too... I'm a homeowner with a new Peerless steam boiler.

I see that Rhomar has a product for steam systems... Boiler Pro 903.

Does anyone use it?

Everything Rhomar makes is decent, but my passion after 40 years of experience, with real TSP is so enduring, so positive and the benefits after use so predictable, I will continue to be its advocate forever.

The trace amount inevitably left behind raises pH to almost 8. Anything above 7 (neutral) is a rust preventative.

JMHO.

TSP + Water + Oil = SOAP

Just remember Tri-Sodium Phophate and water and oil will create soap. More knowledge from the navy days.
