Water for the Boiler | Spirax Sarco

There is a need for the boiler to operate under the following criteria: Freedom from scale - If hardness is present in the feedwater and not controlled chemically then scaling of the heat transfer surfaces will occur reducing heat transfer and efficiency - making frequent cleaning of the boiler necessary. In extreme cases local hot spots can occur leading to mechanical damage or even tube failure.

Problems in industry due to water hardness - Arveng ...

The degree of hardness is classified as follows: The main problem associated with hardness is scale and deposits formation. Even levels as low as 5 to 8 mg/L are too extreme for many uses (i.e. as boiler feed water). Hardness and in particular calcium tend to precipitate coupling with anions like carbonate phosphate or sulphate.
