Marine Engineering: Boiler Water TestingRegular boiler water testing is essential to ensure that a good chemical oxygen scavenger reserve is maintained at all times. Controlling condensate system corrosion Dry steam is not corrosive, but once it condenses again to form water, it can adsorb the corrosive gases, oxygen and carbon dioxide, which if not adequately treated can lead to rapid failure of condensate return lines.chemical boiler - Search, Compare and Save24/6/2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good.

Boiler Water Treatment Part 2 – Internal Treatment

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.

These boiler treatment chemicals ensure that any hardness slippage is converted into a mobile sludge which can be removed by steam boiler blowdown and so doesn't form boiler scale. If a boiler water softener fails, scale formation can occur rapidly, so it is important that the water treatment tests include a daily test of the water softener.
