FINEAMIN 15 is a special combination of surface active, alkalizing polyamines and polyacrylates, used in stewing and boiling out steam boilers, an environmentally compliant product meant to replace dangerous acid and caustic soda chemical cleanings.

Existing corrosion products and deposits from old boilers as well as grease, oil, mill scale and ferric oxides found in new boilers are easily dispersed and gently removed. Along with the boiling out, long term use of film-forming FINEAMIN 15 water treatment chemical gives the advantage of online cleaning and reduces the need for chemical cleaning at many utilities, extending the period between cleanings by years or totally cancelling them.

FINEAMIN 15 is generally injected as a diluted solution, during the filling process. This can be done by using a dosing pump or directly into the steam drum before closing the boiler. During the process, the boiler can be bleeded off in regular intervals. For additional make up water, product has to be added respectively (maintenance dosage). Therefore, a dosing pump is recommended (see procedure).

What is the recommended dosage of FINEAMIN15 for the alkali boil out procedure?

Depending on the system, boiling out can be done in one or two rounds.

For the first boiler boil out, it’s recommended to use 2 to 4 l/m3 of boiler volume. As an example, a maximum of 132 l  to 33 m3 of boiler water. During boiling, the maintenance dosage is 1 to 2 l/m3 of feedwater. For the second boil out, the recommended dosage for the boiler boil out chemicals is 1 to 2 l/m3 of boiler volume. As an example, with a maximum of 66 l to 33 m3 of boiler water.

FINEAMIN 15 is delivered as liquid solution in drums of 30 kg, 60 kg or 210 kg. The product is also available in standard IBC containers of 1000 kg. In closed drums, with an ambient temperature ranging from -5°C to 45°C, it can be stored for up to 5 years.
