Spray Scrubber Deaerators
Spray Scrubber Deaerator
Ecodyne spray-scrubber deaerators are used when there is a requirement for significant heating steam. They have the same oxygen removal ability as spray-tray units and are lower in cost. The effectiveness of deaeration in an Ecodyne Spray Scrubber Deaerating Heater is the result of many design features including two stage deaeration, counter-current flow of steam and water and a specially designed scrubbing chamber. Each unit is individually built for specific service conditions using the experience gained from hundreds of installations worldwide. This allows us to fully guarantee and meet your specifications.
The first stage of the spray scrubber is identical to that of the spray-tray unit with 95% of the non-condensable gases removed in the spray section. The spray valves are arranged so that the water does not strike any metal surface of the unit until these gases are removed.
The sprayed water enters the second stage scrubber section where it is vigorously mixed with a large excess of fresh oxygen-free steam. In this stage the water is heated to the temperature corresponding to the saturated steam pressure in the deaerator. As the steam and water rise upward through the baffled scrubber, the violent action frees the remaining non-condensable gases from the water. Proper design of the scrubber passages ensures complete deaeration without noise or vibration.
The steam carrying with it the non-condensable gases rises up through the steam duct to the first stage spray section. Here, as with the spray-tray units, the vent condenser ensures minimum steam loss. An Ecodyne Spray-Scrubber Deaerator is guaranteed to give the same oxygen removal and venting loss as a tray-type deaerator – and is often considerably lower in price.
