MIL-B-3242B Marine/ Navy Ship Boiler Compound treatment of boiler feed water

MIL-B-3242B is used in the treatment of boiler feed water for marine boilers on Naval vessels. Meets the requirements of Military Specification 

Advantages

Economical for use highly active phosphate based compound. Dissolves easily in water for dosing.

Eliminates scale problems due to calcium.

Maintains sludge in a non – adherent state for ease of blow down. Simple test to determine level of treatment.

Can be used for boilers of all pressures.

The alkalinity in the system is not influenced by MIL-B-3242B

Usage

MIL-B-3242B is formulated to form a precipitate with calcium ions, which will not adhere to metal surfaces but are in a form suitable for blowdown.

Dosage

MIL-B-3242B is used in controlled amounts so that a free phosphate level is maintained in the boiler. This level is determined by the boiler pressure.

Initial dosage is 30-50 gr. per ton of water and depends on the quality of feed water.

Dosing Method

For best results dose MIL-B-3242B directly to the boiler via the bypass pot – feeder.

The dry powder should be dissolved in hot water (50^o C) at a ratio of 1 part powder to 20 parts condensate (e.g. 500 grams/ 10 liters). Ensure that treatment is fully dissolved before dosing.

Sample and testing

A representative sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blowdown, cooled and tested immediately.

Maintain phosphate level 20-50 PPM depending on the boiler pressure.

USE THE TABLE:

Select the section corresponding to the pressure of the boiler to be treated and read across the table to obtain the level of treatment required.
