In order to prevent industrial boilers from oxygen corrosion

the atmosphevic thermal deaerators are commonly used. Owing to the fact that the atmospheric thermal deaerators should be highly positioned

the application of them on industrial boilers has been limited. But the low - positioned atomospheric thermal deaerators can overcome the limit created by the atmospheric thermal deaerators which must be highly positioned

making the application of atmospheric thermal deaerators to be widened

and being convenient to install

debug and repair.
