The function of a boiler is simple. It boils water to produce steam, which, in turn, provides energy. While this is a straightforward process, there are complexities within it that could affect the boiler’s integrity. The primary concern is the quality of the water.

Even high-quality water contains impurities, which has the potential to create problems for the boiler’s functionality. Over time, chemical impurities in the water could damage a boiler’s internals, leaving solid deposits, such as corrosion, rust or scale as the steam evaporates. These accumulated deposits could eventually thermally insulate the boiler’s heat exchanger surfaces, reducing the boiler’s rate of steam generation and eventually causing the equipment’s metals to fail. Without proper treatment, corrosion, rust and scale may eventually lead to thermal failure, reduced boiler efficiency and a potential boiler failure.

The boiler is not the only thing that may be affected by untreated feedwater. Aside from the boiler’s internals, the corresponding safety equipment and auxiliary piping may also suffer the effects of water chemicals and impurities. Addressing the quality of the feedwater becomes imperative. Otherwise, the damage to the boiler and associated equipment may shorten their longevity and increase capital expenditures.
