Boiler water specifications for natural circulating boilers Working pressure bar(g) 1 < 22 >22 < 44 Properties colourless, clear, free from suspended matter and foam pH-value at 25°C 10.5-12 10.5-12 10-11.8 Sum of alkaline earth elements (Ca + Mg) 2 mmol/l < 0.02 < 0.02 < 0.01 °dH < 0.112 < 0.112 < 0.056" Conductivity at 25°C µS/cm < 5000* < 5000* < 2000* Acid capacity KS 8,2 3 (p-value) mmol/l 1-12 1-12 0.5-6 Carbon dioxide (CO 2 ) dissolved mg/l < 25 < 25 < 25 Iron (Fe), total mg/l -- < 0.05 < 0.03 Silicate acid (SiO 2 ) mg/l < 150 < 100 < 50 Phosphate (P 2 O 4 ) 4 mg/l 10-20 5-10 5-10 Sodium sulphate (Na 2 SO 3 ) 4 mg/l 5-10 5-10 3-5 (Polyamide) 5 mg/l (3-5) (3-5) -- 1 Take care to maintain the allowed value of acid capacity - at this point the allowed conductivity has to be lower on many plants; for water level electrodes minimum conductivity > 5 μS/cm 2 Noted in the past at °dH, changing factor: 1 mmol/l = 5.6 °dH (German hardness) 3 Noted in the past as p-value, changing factor: KS 8.2 = 1 according p-value = 1 4 Measurements only necessary if dosing chemicals are used which contains these values 5 It is recommended to use Amine (film producing) only instead of other dosing chemicals for boilers which have a small heating load and up to maximum 16 bar(g) working pressure. Because of the danger of foam production overdosing is not permitted! ECOTHERM Steam Solutions 35
