Boiler – Fundamentals and Best Practices

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. Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers.

in boilers and feedwater tanks, the water should be thoroughly mixed with an adequate amount of oxygen scavenger and heated to boiling while being vented to drive off oxygen at the start of storage. 3.3 Acid Corrosion 3.3.1 Raw water, as received through the city mains or wells, contains impurities including carbon dioxide.
