Boiler Water Treatment Considerations - Banks Engineering

The ABMA specifies limits, as listed in Figure 5, for boiler water composition with respect to operating pressure to assure good quality steam. While there are other considerations (such as corrosion and deposit formation) in establishing boiler water composition, the limits indicate that requirements for feedwater purity become more stringent as operating pressure increases.

Technical Guidance Document: Steam Purity for Turbine Operation

Normal/Target values for feedwater and boiler water remain the same. The primary purposes of this document are to: a) highlight the problems which can exist in steam turbines, b) indicate how these problems occur and can be avoided, c) provide a set of normal steam purity limits that will provide optimum protection for power plants using

BASIC WATER TREATMENT OF STEAM BOILERS

The impurities found in the makeup water will build up in the boiler as the water turns to steam leaving most impurities behind. There are known maximum limits for these impurities, which can and will be surpassed without proper blow down. The maximum concentration allowable by the limits can be expressed as the maximum cycles for that water supply.
