Water Handbook - Preboiler & Industrial Boiler Corrosion

The most common types of oxygen scavenger are sodium sulphite and sodium bisulphite, other organic chemicals may also be used. 3 To control deposition Any deposits in the boiler can only come from the feed water. Control of the deposits is of high importance to maintain the efficiency of the heat exchange surfaces within the boiler.

Sulphite vs Tannin Oxygen Scavenger Treatments

One method used to reduce the amount of oxygen in boiler feed water is to maintain as high a temperature as possible. This is because increasing the water temperature can drive off the oxygen in gaseous form. It is therefore essential to ensure good feed tank design, and that as much condensate as possible is returned to the system.

Boiler Water Oxygen Scavengers A chemical oxygen scavenger is used to remove the residual oxygen from the boiler feed water in order to protect not only the boiler but also control corrosion in the hotwell (or feed tank) and the condensate return lines.

All combustion processes require the correct oxygen to fuel ratio as it directly effects boiler efficiency. Too little oxygen results in incomplete combustion creating harmful emissions. Setting the boiler to burn with excess oxygen is the normal solution to reducing emissions.

Oxygen is highly corrosive when present in hot water. Even small concentrations can cause serious problems: iron oxide generated by the corrosion can produce iron deposits in the boiler. Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen

All good boiler water treatment regimes include a chemical oxygen scavenger to remove the residual oxygen from the boiler feed water in order to protect not only the boiler but also control corrosion in the hotwell (or feed tank) and the condensate return lines.

WTPS28 is a convenient liquid oxygen scavenger and is recommended for use in steam boiler plant, feedwater storage tanks and closed circuit heating systems. WTPS28 provides corrosion control by scavenging oxygen and by forming a protective iron/tannate film. Scale control is also provided by disrupting crystal growth.
