PROBLEM
SCALE
|
Scale
is an extremely hard substance created when mineral salts come
out of solution as their solubility drops with a rise in water
temperature. Scale-forming salts adhere directly to heating
surfaces forming layers of insulation on the metal
substantially decreasing its heat transfer efficiency.
|
 |
 |
While
1/16th-inch thickness of scale in a fire tube boiler will
increase fuel consumption by 12.5% — any accumulation is a
problem. Scale results in metal fatigue/failure causing
overheating, energy waste, high maintenance costs and
unnecessary safety risks.

SOLUTION
ICI-701
range of scale inhibitors
Impurities
dissolved in BFW (Boiler Feed Water) can form scale
by precipitation directly on the metal surface of the boiler or, when
the impurities are in the form of sludge or suspended matter, they can
deposit on the tube surfaces. In addition to causing overheating of
boiler tubes, boiler scale can cause under deposit corrosion.
The
basic approach in preventing boiler scale and in counteracting
problems associated with deposit formation involves the following:
Maintaining
boiler water phosphate or chelant, alkalinity, and oxygen scavenger at
acceptable values to minimize deposition
and to prevent corrosion of boiler metal. Preventing corrosion in the
system, which generates scale-forming products, by removal of the
oxygen from the feed water and by holding the feed water pH between
8.2 and 9.5.
Preventing
excessive corrosion products from entering the feed water via the
condensate by reducing carbonate and bicarbonate alkalinity in the
feed water, and/or by using neutralizing or filming amines as
corrosion inhibitors, as required, preventing corrosion in the
condensate system.
PRODUCT
CHARACTERISTICS
ICI-701
is based upon a combination of phosphate conditioner and alkalinity
builder. It reacts with feed water hardness and prevents it from
precipitating on the boiler metal as scale.
ICI-702
is a combination of sludge conditioner with a dispersant along with a
pH booster. It minimizes total hardness & Inhibits scale formation
and also condition suspended particles, which is easily removed during
blow down.
ICI-703
Contains
a dispersant, which produces a fluid sludge and ensures easy disposal
through normal blow down. It also contains an alkalinity source, which
helps maintain alkalinity level in the boiler.
ICI-705
is a low
molecular weight polymer along with anti scalant and sludge
conditioners. It conditions any suspended matter such as hardness
sludge and make it non-adherent to the boiler metal. Which is
easily removed with blow down water.
DOSAGE
& FEEDING :-
The
type of Boiler, quality of water and other relevant factors determines
dosage. We will provide technical assistance and will suggest
particular product, its dosage, in accordance with your plant
operating conditions and quality of water.
BLOWDOWN
:- It
is essential to blowdown the boiler at regular intervals to ensure
removal of sludge from the system. This will also prevent the
total dissolved solids from exceeding the prescribed limits. The
frequency of blow down will depend upon the quantity of hardness
entering the boiler through feed water.
HANDLING
:- Avoid
contact with skin, eyes & clothes. In case of contact wash with
plenty of water.
PACKING
:- 50
& 200 Liters. H.D.P.E. Containers.
