Water Quality in Steam Boilers

Date: 09-15-2015 Author: ailsa from ZG boiler

Steam Boiler water is the liquid phase of steam within a Steam Boiler. Water qulity in steam boilers are more and more important. The term may also be applied to raw water intended for use in Steam Boilers, treated Steam Boiler feedwater, steam condensate being returned to a Steam Boiler, or Steam Boiler blowdown being removed from a Steam Boiler.Then, it will need water treatment for boilers.

Characteristics of Steam Boiler feed water

Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure. The steam is capable of carrying large quantities of heat. These unique properties of water make it an ideal raw material for heating and power generating processes.
All natural waters contain varying amounts of dissolved and suspended matter and dissolved gases the amount of minerals dissolved in water varies from 30 g/l in sea water to anything from 0.005 to 1500 mg/l in fresh water supplies. Since water impurities cause Steam Boiler problems, careful consideration must be given to the quality of the water used for generating steam.
The composition of Steam Boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the Steam Boiler, without exceeding the tolerance limits of the particular Steam Boiler design. If the feed water does not meet these requirements it must be pretreated to remove impurities. The impurities need not be completely removed in all cases, however, since chemical treatment inside the Steam Boiler can effectively and economically counteract them.

Steam boiler water quality:

Feed-water purity is a matter both of quantity of impurities and nature of impurities: some impurities such as hardness, iron and silica are of more concern, for example, than sodium salts. The purity requirements for any feed-water depend on how much feed water is used as well as what the particular Steam Boiler design (pressure, heat transfer rate, etc.) can tolerate. Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube Steam 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 Steam Boilers.

Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure. The actual maximum levels must be obtained fro the Steam Boiler manufacturer, who will base them on the characteristics of the Steam Boiler in question.
