Thermal Deaerator
I. Purpose of Thermal Deaerator:
The thermal deaerator is a device used to remove oxygen from the boiler water, protecting the boiler from oxygen corrosion.

Compared to spray plate-type thermal deaerators, the following advantages are offered:
When the same output is achieved, the membrane deaerator is smaller in volume and lighter in weight, reducing costs.
High output range, stable deoxygenation efficiency.
Highly adaptable to water temperature, such as in room temperature conditions, the oxygen content in the water still meets the requirements.
Short time from startup to normal operation.

The thermal deaerator heats the boiler feed water to the saturation temperature at the corresponding deaerator working pressure, removing oxygen and other gases dissolved in the feed water, to prevent and reduce corrosion in the boiler feed water pipes, economizers, and other auxiliary equipment.
The thermal deaerator has been proven to have the following advantages after being in operation and use in hundreds of power plants:
High deoxygenation efficiency.
2: Operation stable with no vibration. Even with a sudden 25% load change, a 10% sudden water replenishment, and a drop in water temperature, the deaerator remains vibration-free and there is no boiling.
3: In addition to good adaptability with minimal requirements for water quality and temperature, it can operate at around 50% beyond its rated capacity. This is particularly evident in heating unit sets and deaerators with slide-pressure operation, where its superior performance is further highlighted.
4: Steam volume less than 0.1% of the inlet water volume; no additional exhaust cooler required. Consumes 1/3 less energy than other types of deaerators with the same output, optimizing the equipment and reducing heat consumption.
