After softening and desalination, the water still contains some air such as oxygen which will harm the boiler body and rust some pressure parts. This way the boiler can not work long and normally. Thermal spray deaerator could remove out the oxygen air. When the water temperature higher, the oxygen is less in quantity. When water is boiled inside, no oxygen stays inside and water press is zero. Water is pulverized through special stuff. When the steam reached 104℃, oxygen and other gas will be leaked.  
  
The thermal spray deaerator we design can remove oxygen by 2 stages. First stage is heating which can collect some oxygen. Second stage is to remove out oxygen by special stuff. The system has two control functions. One is to control temperature. The other is to control water level. It is popular in industry, power plant and metallurgy.
