Why recommend ammoniated citric acid for the

Chemical cleaning of the boiler. We have seen how a new, clean boiler can accumulate copper and magnetite which requires removal. There is a method we propose to do this. Using ammoniated citric acid and an oxidizing agent such as sodium nitrite or bromate, we will now show how this can be achieved.

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.
