Effects of Presence of Dissolved Gases in Feed Water

The removal of oxygen by heating (e.g direct steam injection) reduces the requirement of expensive oxygen scavenging chemicals (most often sodium sulphite), the addition of which actually leads up to increased feed water TDS and longer blowdowns. Direct seam injection is one of the most efficient methods for boiler feed tank heating.

Expansion Tanks | Rite Engineering & Manufacturing Corp.

An expansion tank is required on all closed loop heating boiler systems. As a boiler heats the system water, the water will expand in volume. Water cannot be compressed but air can, so an expansion tank uses air (or an inert gas like nitrogen) that acts like a cushion or spring against this force. It is vital that the pressure in the system does not approach the boiler relief valve setting or
