Characteristics


Characteristics

Affects the structure of the protective magnetite layerin the boiler so to increase protection

Reduction of boiler water blow-down rate

The system is protected against corrosion through protective polyamines

Dispersion of sediments, gratings, dirt, mineral salts and iron oxide

Energy-saving thanks the improved heat transfer

The salt content in the system is not increaseddecline of the blow-down rate

Alkalises the entire steam system including condensate recirculation and feed water system

Hardness stabilization and protection against new sediments

Advantages

Water and Energy Savings: reduction of the blow-down rate

Efficient, because FINEAMIN® avoids any kind of corrosion, your Capital Plant is protected

Protects with a monomolecular protective layer all parts of the plant

Scale and deposit inhibition, online dispersing action of old deposits

Avoids and controlles magnetite growth andmagnetite sludges

Easy to use: FINEAMIN® is injected in 99% of the plants with only one dosing station

Economic: low dosing rate and very low maintenance costs

Environment friendly (no phosphate and hydrazine)

Increase of the boiler durability

Mode of operation


After treatment of the iron strips with 20 ppm FINEAMIN® the surface of the metal showed a continuous protective, dense hydrophobic layer – With repeated treatment thefilm became denser.

Stewing and Blow-out


Stewing and Blow-outFINEAMIN®

Stewing and Blow-out of

Steam Boilers with

FINEAMIN®



-Easy handling and working with FINEAMIN®

- Reduced safety requirements (only safety goggles and protective gloves) whenfilling the system

-No storage regulation (WGK 1)

- Disposal conditions of the local authorities can be met without problem (pH - value, CSB, TOC etc.)

- More thorough cleaning of the plant of grease, oil, rolling skin and iron oxides by thespecial combination of "film forming" polyamines and polyacrylates

-Formation of a good magnetite protective film already during stewing

- Steam purity is achieved with considerably fewer blow-out cycles leading to timeand, in particular, cost savings

-Shortening of rinse and idle periods also results in a reduction of operating costs

Disadvantages of the classic methods

Trisodiumphosphate: difficult to dissolve in the watercan result in phosphate deposits in the tubes no dispersing capabilitiesnot volatileproblematic disposal into water or sewage systemtendency of foaming when over-doseddanger of hide-out effectlonger blow-out times

Bicarbonate lye or caustic soda: no dispersing capabilitiesnot volatileproblematic handlingcaustic burnsdanger of stress corrosions crackingrather long blow-out period

Demineralised water: no dispersing capabilitiesno cleaning capabilityrather long stewing and Blow-out period, not volatile



Effect of FINEAMIN® on the Surface of C-Steel

Experiment: The surface of an iron sheet was polished and subjected to various water conditions in a laboratory autoclave:

1. demineralised, deaerated water, alkaline

2. as above, but with 20 ppm FINEAMIN®

After every step the water was changed.
