The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.

Oct 11, 2015 · Chloride forms complexes with many transition metals. This can (and will) dramatically increase corrosion. In addition chloride will also increase conductivity. Chloride tends to be particularly corrosive with high hydrogen ion concentration. Above a certain level it makes "briny" tasting coffee, I grew up in area with water like that.

The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be

The increasing level of the TDS is known as "cycles of concentration.". This term is used very often in the operation and control of a boiler system. A water supply that contains 175 ppm of TDS in the make-up water could be concentrated 20 times to 3500 ppm. The maximum amount of TDS allowed in a low-pressure boiler is 3500 ppm.
