The deoxygenation effect is not satisfactory
Thread Content
What are the reasons for the high oxygen content in the deaerator? In our facility, the temperature of the deaerator fails to rise; the pressure is quite high at 60 KPa, while the temperature remains only at 98 degrees. Please analyze this situation – do you have any effective solutions? Thank you!
The temperature should be 105 degrees, plus or minus 2 degrees
Thermal deoxidation involves heating water to its saturated temperature at that pressure; as the water gradually evaporates, the vapor pressure above the water surface increases, causing other gases present in the water to be released. Pressure and saturation temperature are proportional; in other words, if the water is not saturated at that pressure, oxygen cannot be completely dissolved out. The temperature is too low; it needs to be increased. Generally, the pressure is kept at 20 KPa while the temperature is set at 104
Check whether your deaeration head is designed to be too small or if there is blockage in the packing inside it.
First, address the issue of high pressure; the cause can only be found on-site.
The cause was investigated on-site; it might lie in the packing inside the deaeration head.
