OXYGEN SCAVENGERS
BOILER FEED WATER PREPARATION
Oxygen corrosion of metals is a serious problem in the operation and maintenance of industrial boilers and steam generating plants. In order for systems to be in good condition and operate at optimum efficiency, the correct water parameters must be maintained permanent. This can be achieved with carefully selected oxygen scavengers designed specifically for boiler feed water treatment.
Residual oxygen in the feed water is an aggressive corrosive factor and must be removed to ensure the reliability and long life of boiler equipment. IFO oxygen scavengers include various types of reagents that are selected individually for each system, which allows to solve the problem of feed water deaeration most effectively.
| Product | Toxicity | Absorption | Deposits formation | Volatility | Recommendations for use |
|---|---|---|---|---|---|
| IFO Diethylhydroxylamine | low | average | Does not form deposits. Does not increase the boiler water salinity. | Fugitive. Provides protection for the vapour-condensation path. Forms a passivating film. | Medium and high pressure steam boilers, closed heating systems. |
| IFO Carbohydrazide | medium | ||||
| IFO Bisulfite | low | high | Produces deposits. Increases the boiler water salinity. | Non-volatile. Does not provide protection for the vapour-condensation path. Does not form a passivating film. | Low and medium pressure steam boilers, closed heating systems. |
BENEFITS
Controls the formation of oxygen corrosion in boiler feed water
Extends equipment life and reliability
Reduces maintenance costs
Minimizes the content of iron and copper in feed water and condensate, reducing the entry of corrosion products into the boiler
Does not contaminate products in contact with steam
Individual selection of the reagent and its correct dosages
IFOTOP’s product portfolio includes solutions for efficient water treatment and sanitation. We produce reagents both for circulating water supply systems and for the preparation of boiler feed water. Also, our team has created a reagent supply system, thanks to which water treatment is fully automated and optimized.
