Why recommend ammoniated citric acid for the chemical

Chemical cleaning of the boiler. We have seen how a new, clean boiler can accumulate copper and magnetite which requires removal. There is a method we propose to do this. Using ammoniated citric acid and an oxidizing agent such as sodium nitrite or bromate, we …

Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

May 03, 2011 · The lower zone is deficient in oxygen, so reduction reactions occur. This allows the sulfur in the smelt to occur as Na 2 S and not Na 2 S 2 O 3 or Na 2 SO 4, which would be unsuitable for fresh liquor.About 40%–50% of the air required for combustion is added by forced draft fans at the primary vents at the bottom of the recovery boiler.

May 03, 2011 · The main autocausticizing reaction that occurs in the recovery boiler is between sodium metaborate and sodium carbonate in the molten smelt, which forms trisodium borate. The trisodium borate reacts with the water in the smelt-dissolving tank to form sodium hydroxide and regenerate sodium metaborate ( Björk et al., 2005 ).
