Jet Spray Pressurized Deaerator - Operation

WATER FLOW- Incoming undeaerated water and pumped returns enter the deaerator through a spring-loaded stainless steel nozzle which directs the flow in conical sheets into the steam atmosphere of the direct contact vent condenser. At this point, the water temperature in the deaerator is raised to within a few degrees of steam temperature and most of the corrosive, non-condensable gases are removed. The water is directed by a stainless steel tray section into the Jet Spray atomizing valve. Here a high velocity of incoming pure steam atomizes the water into minute particles. This violent scrubbing action removes the last traces of dissolved gases. The hot, deaerated water then falls to the storage compartment for boiler use.

STEAM FLOW- Steam initially enters the deaerator through a special stainless steel Jet Spray atomizing valve. This valve is designed to fully atomize and provide complete deaeration under all load conditions. This design insures that the purest steam comes in contact with the purest water. Once this high velocity steam mechanically shakes out the last traces of non-condensable gases from the water, it flows upward into the preheated area where it meets the incoming makeup water and pumped returns. This water continually condenses the steam which preheats and releases the non-condensable gases into the internal vent condenser where they are metered harmlessly from the deaerator into the atmosphere. This action causes more steam to be drawn into the system to complete the cycle.
