Vertical Spray Deaerator (Single Vertical Tank)

Kansas City Deaerator Spray deaerators provide an ecomical alternative to tray type units. The units feature a simple, trouble-free, quiet design and are designed for constant loads. Incoming undeaerated water enters the Deaerator through spring-loaded, stainless steel spray valves. These variable orifice valves produce a fine spray in a uniform pattern from 5% to 200% of design. The fine droplets of water maximize the surface area in contact with steam, raising the temperature to within a few degrees of saturation temperature and instantly releasing the majority of the corrosive, non-condensable gases. The preheated and partially deaerated water is channeled through a collection basin downcomer, through a tortuous path second stage deoxygenator. Here the hottest, purest steam vigorously scrubs the water to heat it to the saturation temperature and strips the last traces of dissolved gases.
