The feedwater deaerating plant, consisting of the feedwater
tank SW and the deaerator dome NDR, removes dissolved
gases such as oxygen, carbon dioxide and other non-condensable gases from boiler feedwater and make-up water.
For the operation of steam boilers with high thermal load
on the heating surfaces boiler feedwater that is treated and
conditioned according to TRD 611, EN 12952 part 12 or
EN 12953 part 10 must be used.
The boiler feedwater must be free of hardening constituents
in order to prevent the formation of scale on the boiler heating surfaces. The presence of dissolved oxygen and carbon
dioxide causes severe corrosion of metal boiler parts. The
feedwater deaerating plant is custom designed for each
application and meets essential thermodynamic requirements
to achieve optimal performance.
