Sodium Sulphite (sulfite) with Catalyst Powder | RXCHEMICALS

Sodium sulfite is a constituent of some boiler feed water treatments. This constituent acts as an oxygen scavenger. The presence of oxygen in boiler water will lead to corrosion of the boiler . A chelating agent, sodium hexametaphosphate is sometimes added to boiler water to inhibit hard water salts from precipitating to form scale.

Reasons why the water is bouncing in the - Heating Help

Jun 25, 2014 · The boiler is priming or foaming. Priming is the violent bouncing of the water. Foaming happens when bubbles form on the surface of the water. Foaming follows priming, and while priming is bad, foaming is worse. Foaming throws water up into the system and creates water hammer, uneven heating and water level problems within the boiler.
