RECOMMENDED WATER CONDITIONS

It is very important that a strict water management program is followed to ensure trouble free boiler
The following are recommended for feedwater and for boiler water
pH Value
Hardness
Suspended Solids
Chloride
Organic Matter
Oil
Minimum Temperature
pH Value
Hardness
Suspended Solids
Chloride
Oxygen Scavenger, Sodium Sulphite or Tannin 30 to 70 mg/kg.
Phosphate
Total Alkalinity
Caustic Alkalinity
Total Dissolved Solids (TDS)
Iron
Silica
Dissolved Oxygen
It is critical that the boiler water pH be alkaline in the range 10.5 -12.0
Daily boiler blowdown is essential to help prevent formation of
deposits and reduce Total Dissolved Solids (TDS).
Consult your Water Treatment specialist to establish the frequency and
duration of blowdown required to achieve the required conditions.

operation.
FEEDWATER
(water entering boiler)
8.5 to 9.5 tested at room temperature.
less than 2.0 mg/kg in the form of CaCO
None.
Less than 50 mg/kg.
Less than 5 mg/kg.
None.
85°C
BOILER WATER
(water inside boiler)
10.5 - 12.0, tested at room temperature.
Not detectable.
Less than 200 mg/kg.
Less than 500 mg/kg.
Less than 50 mg/kg, in the form of PO
Less than 1000 mg/kg.
300 mg/kg as minimum as CaCO
Less than 3500 ppm.
Less than 1 mg/kg.
Less than 150 mg/kg, in the form of SiO
None.
mg/kg = Milligrams per Kilogram
CaCO = Calcium Carbonate
3
PO = Phosphate
4
SiO = Silicon Dioxide

1 Grain hardness = 17.118 ppm
therefore 70 ppm = 4.10 grains hardness.
For practical purposes mg/kg = ppm
