May 02, 2000 · water by softeners. Their removal dramatically reduces the possibility of boiler scale formation. Water softening can be performed by ion exchange, whereby favorable sodium ions are exchanged for unfavorable calcium and magnesium hardness ions by the ion exchange resin beads. Eventually, the softener resin bed exhausts (fills up with
Boiler Water Treatment Water Softener . 2/18/2014 5 Basic Boiler System Makeup External Treatment Steam Vent Blowdown Feedwater Return Condensate Steam Heat – With low temperatures and high oxygen content, the corrosion rate on carbon steel can be excessive.
BASIC WATER TREATMENT OF 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.

Apr 01, 2021 · Most of the boilers in large industrial plants are the watertube style, frequently of the package type, although large boilers may be field-erected. Steaming rates (pounds per hour [lb/h]) are usually in the five to six-figure range.
Water treatment for industrial steam boilers
Determine Flow Rate of softener using method C or D below: C. Boiler Horsepower x 4 gallons per hour + estimated rate of blow-down in G.P.M. = G.P.M. required. D. Pounds of Steam per Hours divided by 8.345 divided by 60 minutes + estimated rate of blow-down in G.P.M. = G.P.M. required.
According to the Water Quality Association, the ion exchange softening process adds sodium at the rate of about 8 mg/liter for each grain of hardness removed per gallon of water. A "grain" of hardness is equal to 17.1 mg/l or ppm of calcium carbonate.
