As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.

BASIC WATER TREATMENT OF STEAM BOILERS

Feed-water purity is a matter both of quantity of impurities and nature of impurities: some impurities such as hardness, iron and silica are of more concern, for example, than sodium salts. The purity requirements for any feed-water depend on how much feed water is used as well as what the particular boiler design (pressure, heat transfer rate, etc.) can tolerate.

Water Handbook -Boiler Deposits: Occurrence And Control | SUEZ

Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.

Another reason to monitor water usage is that high water usage will hasten scaling when the water has a high mineral concentration (hard water). It's useful to note that the level of water hardness varies throughout the United States and Canada, and depending on a boiler's location, high water usage has been known to result in scaling within a matter of weeks (see graph below).
