  • Steam Boiler: Calcium and Magnesium Hardness

    Water hardness can be classified based on metal ion namely calcium hardness and magnesium hardness. Most of natural water has calcium and magnesium hardness due to calcium and magnesium ions. Calcium and magnesium hardness often need to be known to determine amount of lime and soda ash which is needed in the process of water softening (lime-soda ash softening).Learn More

  • Using hot water tap to manage steam boiler water concentration

    Nov 21, 2020 · In a steam boiler with 1.5 liters of water, at the end of the week you will have built up a mineral content equivalent to 2.2 liter of feed water inside the boiler, a concentration factor of about 1.5. So if your feed water had a hardness of 50 mg/l, the hardness in the boiler should have risen to 75 mg/L by the time you drain/flush it.Learn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Learn More

  • Chemical Treatment Requirements for Steam and Hot Water

    Jun 12, 2017 · A normal guarantee for steam quality is 0.5% moisture. However, this moisture is boiler water. If the boiler water contains 2,000 ppm of dissolved solids, 0.5% moisture or one half pound of boiler water per 100 pounds of steam would result in a concentration of 10 ppm solids in the steam.Learn More

  • Boiler Feedwater - an overview | ScienceDirect Topics

    Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of Learn More
