EP0567275A2 - Carbohydrazones in the treatment of boiler water …

Deaerator System. The DeOxy deaerator removes dissolved gases such as oxygen in the boiler feedwater. It allows substantial savings in the use of chemicals and in the number of blowdowns required. A deaerator will prevent the corrosion in the system and in the boiler. Oxygen is the main cause of corrosion found in steam systems.

Boiler Feedwater Deaeration: How To Keep Your Steam System …

How boiler feedwater deaeration is done. Water at 70°F could contain oxygen at 8.6 ppm and water at 150°F could contain oxygen at 4.3 ppm. Oxygen content of 7 ppb is generally accepted by the ASME, but your boiler supplier should specify what level is ideal for operating their equipment. Heat is the most common method for removing oxygen.

Meanwhile, steam rises up through the perforations, removing the gases before the feedwater flows into the storage tank and is released into the boiler system. Vacuum Deaerators: Instead of heating the feedwater to its saturation temperature before stripping away gases, a vacuum deaerator is designed to boil the water at a lower temperature.
