Boiler water

Check the design specifications for small and medium-sized thermal power plants; this specification should be available online
Check it out – the book on power plant water treatment technology; it contains very detailed explanations
Check the standards; in short, desalination and deoxygenation are required to meet the corresponding specifications.
Softened water should be used. We use Xiechang’s water softening equipment.
Hehe, for deoxygenation and desalination, just refer to the **specifications** based on factors such as the boiler’s pressure rating.
The test items should include: the pH value of boiler feedwater and makeup water, as well as silicates； Oxygen content in the feed water.
Boiler water is such a hassle – we draw it from river water, purify it, soften it using ion exchangers, add chemicals from dosing tanks, and conduct regular inspections on a monthly basis.
The water used in boilers must be treated with sulfonated resin to remove ions such as calcium and magnesium, thereby preventing scaling in the pipes and avoiding impacts on heat transfer efficiency
These are the parameters for boiler feedwater testing: pH (8.8–9.3), SiO2 (≤20μg/L), conductivity (≤10μs/cm), dissolved oxygen for AV-201A (15≤μg/L), dissolved oxygen for AV-201B (15≤μg/L)
Water quality standards for low-pressure boilers (GB1576-2001, 2001) – Water quality for industrial boilers; replaces GBl576—1996
