In the operation of boiler water treatment system, chemical deoxygenation is the core process for preventing and controlling oxygen corrosion of pipelines and furnace bodies, and ensuring stable operation of boilers.

Dissolved oxygen in water is the main cause of oxygen corrosion in boiler feedwater pipelines, economizers, and steam drums. Boiler deoxygenation agent is often used as a thermal deoxygenation supporting method or an independent chemical deoxygenation scheme. Whether the dosing method is standardized directly affects the deoxygenation effect, agent utilization rate, and long-term operation stability of the boiler.

Water treatment equipment often operates in humid, humid, and prone to condensation environments such as water plants, sewage treatment stations, chemical workshops, water purification plants, and outdoor pump rooms. The electrical components such as distribution panels, contactors, relays, frequency converters, sensors, and line terminals that come with the equipment are prone to moisture, condensation, and water ingress problems when exposed to high humidity environments for a long time.

The dissolved oxygen contained inside the boiler feedwater is a common cause of corrosion in the boiler body, heat exchange pipes, and condensing pipes.

Industrial circulating cooling water systems are widely used in industries such as chemical, power, metallurgy, manufacturing, and central air conditioning. During long-term operation of equipment, continuous concentration of water can lead to enrichment of calcium and magnesium ions, imbalance of water quality acidity and alkalinity, and easily cause problems such as scaling and metal corrosion in pipelines, heat exchangers, and cooling tower walls.

Boiler water treatment is the core process that ensures the safe and stable operation of thermal equipment. The complete process includes multiple modules such as pretreatment, softening and desalination, deoxygenation treatment, furnace conditioning, and condensate return water maintenance.

In the operation and maintenance of water treatment systems such as circulating cooling water, reverse osmosis pure water, and industrial wastewater, dispersants and scale inhibitors are commonly used water quality stabilizers. Many operation and maintenance personnel may have questions: both are liquid agents in appearance, which can alleviate pipeline scaling and water turbidity problems. Can they be replaced by each other in daily use? The answer is clear: water treatment dispersants and scale inhibitors cannot replace each other.

There is continuous dissolved oxygen inside the boiler water circulation system, which can cause electrochemical corrosion to metal components such as the boiler steam drum, water-cooled wall, pipeline, and economizer. Long term operation can easily lead to problems such as thinning of the pipe wall, pitting, perforation, leakage, and shutdown, shortening the service life of the entire thermal equipment.

Surface water, groundwater, and municipal tap water generally contain calcium, magnesium, bicarbonate, sulfate, and silicate ions. During reverse osmosis filtration, water molecules pass through the RO membrane, and various salt ions are trapped on the concentrated water side, increasing with the concentration factor

In water treatment systems such as industrial circulating water, pure water preparation, central air conditioning, and boiler water supply, water bodies generally contain mineral components such as calcium, magnesium ions, and bicarbonate ions.

Boiler deoxygenation agent is a key chemical to ensure the safe and stable operation of boilers. It is mainly used to remove dissolved oxygen in boiler water, prevent corrosion and scaling of the boiler inner wall, and extend the service life of equipment.

During the operation of the boiler, dissolved oxygen in the water can corrode the metal tube walls of the boiler, causing thinning and damage to the tube walls, shortening the service life of the boiler, and even posing safety hazards.
