4/5/2016 · A boiler that makes up 4000 gal/day of water having 100 ppm of hardness, has a potential of accumulating over 1000 pounds of scale per year. Alkalinity Test In natural waters, alkalinity is most commonly the result of bicarbonate and carbonate ions; in treated waters, alkalinity may also be contributed by hydroxide, phosphate, silicate, and other treatment ions.

Feed Water Treatment to Avoid Corrosion

Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Corrosion is a major problem in steam systems with high consumption of make-up water. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems.

Removing Oxygen from the boiler is done by two steps, firstly the hotwell feed water temperature should be kept above 80oC as this will remove the majority of oxygen dissolved in solution. The second step is to treat the water with an Oxygen Scavenger such as Tannin or Sulphite which will remove the remaining O2.
