Boiler – Fundamentals and Best Practices

Whether distilled or raw (city) water is used for boiler make-up, chemical treatment is necessary to counteract harmful substances which are present. Particularly, the contaminants present in raw water are inorganic sodium compounds of chloride, sulfate and carbonate and the hardness (calcium and magnesium) compounds of these same materials. Gases such as oxygen and carbon dioxide are present in feed water, distilled or row water. Marine evaporators do not remove all of the salts and minerals from seawater. Minute particles are carried over from the evaporator in the water vapor and are present in the distillate. Any leaks in the distiller, condensers or any part of the feed system which is sea water …
