How & Why Are Water Softeners Used in Steam Boilers

Therefore, when a raw water supply of 600 ppm TDS is diluted with 0 ppm TDS water at a one-to-one ratio, the result would be 300 ppm TDS. This would represent a dilution of 50% or a condensate return of 50%. The final step in our gathering of data for the softener selection process is to obtain the number of hours in a day the boiler is operated.

CHAPTER 39 BOILER WATER TREATMENT

water chemistry is essential to the power engineer who continually strives to increase the efficiency of the boilers and steam-using equipment. The pressure and design of a boiler determine the quality of water it requires for steam generation. Municipal or plant water of good quality for domestic use is seldom good enough for boiler feed water.

Boiler Water Quality

Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.
