Do It Yourself - Boiler Treatment

Feed water conductivity should be less than or equal to the conductivity of the water softener stream. High feed water conductivity is an indication that liquid is burping from the boiler to the steam lines. This can be caused by excessive carbonate levels or poor level control in the boiler.

Boiler Chemistry Control and Treatment of Feed Water

Also high concentrations of deposits cause corrosion. So some treatment of feed water is necessary. Details related to boiler water chemistry can be found in Chapter V of Power Plant Instrumentation and Control Handbook: A Guide to Thermal Power Plants (Here only treatment part is discussed, with special reference to Supercritical boilers.)

Carryover and its Causes - forbesmarshall.com

In boiler water, the presence of free NaOH must be eliminated by practicing coordinated phosphate control. High alkalinity and presence of suspended impurities increase carryover. When the suspended impurities are more, there is a blanket formation over the water-steam interface and this prevents the easy passage of steam bubbles from the

THE ELECTRICAL CONDUCTIVITY OF WATER

While the electrical conductivity is a good indicator of the total salinity, it still does not provide any information about the ion composition in the water. The same electrical conductivity values can be measured in low quality water (e.g. water rich with Sodium, Boron and Fluorides) as well as in high quality irrigation water (e.g

That oxygen comes out of solution as the water boils, and it can eat holes in the boiler, right at the boilers waterline. If you decide to feed with hot water instead of cold water, the minerals in the water will come out of solution on the automatic water-feeders seat, and that can cause a flood, especially if its a one-pipe-steam system.
