What is the maximum temperature of an open deareator?

The maximum temperature of an open deaerator typically reaches around 212 °F, which is significant for its operation. Open deaerators are designed to remove dissolved gases (primarily oxygen and carbon dioxide) from water before it enters the boiler system.

At this temperature, water is just at the boiling point at atmospheric pressure. This ensures efficient removal of gases, as heating the water to this point allows for the effective release of dissolved gases into the atmosphere. Maintaining the temperature around this level is essential for optimal performance, preventing corrosion in the boiler and enhancing the overall efficiency of the system.

Higher temperatures would necessitate greater pressure and could lead to complications in design and operation, as well as potential safety issues. Therefore, the 212 °F figure aligns with practical standards and safety guidelines in the industry.
