Boiler Feed Water Treatment Chemicals
Boiler feed water treatment chemicals are chemicals used to treat the water that is fed into boilers to generate steam. These chemicals are added to prevent the buildup of minerals, corrosion, and scaling in the boiler system, thereby improving the efficiency and longevity of the boilers
Overview: Boiler water treatment is a process of treating the water used in boilers to generate steam, with the aim of producing high-quality, treated water that is free of impurities that can damage the boilers and decrease their efficiency. The treatment process typically involves removing suspended solids and dissolved impurities, adjusting the pH levels, removing minerals, removing dissolved gases, adding chemical treatments, and ongoing monitoring of water quality.
​
The final goal of boiler water treatment is to maintain the water in the boilers in a high-quality state, preventing corrosion, scaling, microbiological growth, and foam formation, and improving the efficiency and longevity of the boilers
​
What are the use of water treatment chemicals in boiler?
Chemicals are used for boiler water treatment for the following reasons:
-
To prevent corrosion: Dissolved oxygen, carbon dioxide, and other gases in the water can cause corrosion in the boiler system, leading to costly damage and decreased efficiency. Chemical treatments such as oxygen scavengers are added to remove these gases and prevent corrosion.
​
-
To prevent scaling: Certain minerals in the water, such as calcium and magnesium, can form deposits on the internal surfaces of the boilers, reducing heat transfer and leading to decreased efficiency. Chemical treatments such as scale inhibitors are added to prevent the formation of these deposits.
​
-
To maintain pH levels: The pH level of the water in the boilers needs to be maintained within a specific range to prevent corrosion and scaling. Chemicals such as alkalinity builders are added to adjust the pH levels.
​
-
To control microbiological growth: Microorganisms such as bacteria and algae can grow in the boilers, leading to corrosion and decreased efficiency. Chemical treatments such as biocides are added to control microbiological growth.
​
-
To prevent foam formation: Foam can form in the boilers, leading to decreased efficiency and potentially damaging the boilers. Chemical treatments such as antifoam agents are added to prevent foam formation.
​
By using these chemical treatments, the water in the boilers can be maintained in a high-quality state, improving the efficiency and longevity of the boilers.
