Description for Gestra NDR-SW

Technical Data Service pressure 0.5 barg Service temperature 111 °C Capacity 0.5 m³/h up to 70 m³/h > 70 m³/h on requestDescription 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.
