Controlling TDS in the Boiler Water | Spirax Sarco

An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.

1. Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set back that lowers the operating pressure on steam boilers or operating temperature on hydronic boilers when idling at night or on mild spring and fall days.. 2. Install an Economizer. An economizer uses the otherwise wasted hot flue gas to heat feedwater on its way to the boiler.
