One of the main causes of reduced reliability in boiler systems is
corrosion. This phenomenon is described as the active destruction of
sound boiler metal by the unforgiving action of dissolved oxygen in the boiler
water. It usually results in deep holes, scabs, or blisters that allow the
chemical reaction to continue.
Even though large metal surfaces can be quite sound, an oxygen pitting
site can develop deep corrosion and cause ultimate boiler failure. Untreated
feed water containing oxygen is going to continue to be highly corrosive to
steam boilers so it is essential to keep
adequate chemical reserves of an effective oxygen scavenger to avoid
costly boiler metal corrosion and down time. It is estimated that problems due
to boiler system corrosion cost the industry billions of dollars per year.
The latest innovation from Cortec® Laboratories, Inc, enables
us to offer a new inhibitor addition to our boiler treatment products.
S-10FA is a filming amine formula for corrosion control in boiler condensate
systems. The molecules of S-10FA anchor their hydrophilic heads to wetted metal
surfaces while their hydrophobic tails will shield metal surfaces from contact
with acidic corrosive condensates and prevent corrosion products, dirt, and other
impurities in condensate return system from attachment to the metal. A thin protective
field is formed on the metal when S-10FA is volatilized in the steam stream.
S10-FA is thermo-stable and compatible with a majority of boiler
S-10FA should be added separately from other boiler treatment chemicals
and preferably be injected into the steam header.
S-10FA is very economical. A typical dose is 10 ppm to boiler feed water.
The dosage may need to be adjusted depending on pH and oxygen content in
condensate. The injection quantity should be based on both the internal surface
area and volume of the system.
Cortec’s S-10 FA is available in 5-gallon (19 liter) plastic pails,
55-gallon (208 liter) metal drums, liquid totes, and bulk. The shelf life for
S-10FA is 2 years in closed original container.
