Characteristics of thermal deaerator :
The deaerator is a device used to remove dissolved oxygen contained in the boiler feed water to protect the boiler from oxygen corrosion.
Working Principle Deoxidation of feed water is the main method to prevent corrosion in power station boilers or industrial boilers. In a container, the amount of gas dissolved in water is proportional to the partial pressure of the gas above the water. The main method of thermal deoxidation is used, that is, steam is used to heat the feed water, raising the temperature of the water, so that the partial pressure of the steam on the water surface gradually increases, while the partial pressure of the dissolved gas gradually decreases, and the gas dissolved in the water continues to escape. When water is heated to the boiling temperature under the corresponding pressure, the surface of the water is all water vapor.
The partial pressure of dissolved gases is zero, and water no longer has the ability to dissolve gases, that is, the gases dissolved in water include Oxygen can be removed. The effect of oxygen removal depends on the one hand whether the feed water is added to the boiling temperature under the corresponding pressure, and on the other hand it depends on the removal speed of dissolved gas. This speed has a great relationship with the size of the contact surface area between water and steam
The thermal spray deaerator has the best effect and is directly supplied by Henan manufacturers.
