Deaerator

Desuperheater

Oxygen and Carbon Dioxide in water are very active corrosion agents with respect to carbon steel. It is essential to eliminate them. Deaeration and Degasification can be carried out either chemically (for oxygen), or using physical methods (for all the dissolved gases)

KPE engineered Deaerator types cover all industries demands

Spray-Tray Type Deaerator

The thermal deaerator either atmospheric or pressurized (0.3 bar or more) makes it possible to obtain water of excellent quality with very low oxygen content (lower than 0.01 mg/l) and is used for installations which operate at high output and pressure.

KPE design, according to the physicochemical parameters of operation, optimizes the removal of dissolved gases. The feed water thus obtained is of very high quality.

Spray Type Deaerator

This alternative design, which gives performance close to the thermal deaerator (0,05mg/l), is well suited to boilers of medium output and pressure and constitutes an economic alternative to chemical treatment.

The operating conditions are identical to those of the thermal deaerator but the tower and its fittings are replaced by a dome installed on the top of the feed water tank.

The maintenance of feed water supply at the highest possible temperature commensurate with boiler plant performance plus simple oxygen scavenging chemical treatment is usually acceptable for oxygen control.
