How many tons of boilers require deaerator?

Deaerator is one of the key equipment in boiler and heating system. With the popularization and development of demineralized water treatment technology, deoxidization of boilers and heating systems becomes more and more important.

According to Water Quality Standard for Industrial Boilers, for steam boilers, when rated capacity is greater than or equal to 6 t/h, oxygen removal measures should be taken when local corrosion is found less than 6 t/h. For hot water boilers, when the rated thermal power of the boiler is greater than or equal to 4.2 MW, oxygen shall be removed as much as possible for boilers with rated thermal power less than 4.2 MW.
