Oxygen Control For High- and Low-Pressure Boiler Water Systems

For example, in a high-pressure system, the feedwater quality needs to be very pure and free of dissolved solids to avoid causing scale. Addition of a non-volatile oxygen scavenger such as sulfite will add dissolved solids to the boiler. Besides the increased need to blow the boiler down due to the increased solids (resulting in a direct loss of
