What is a Deaerator?

There is no better place to start than at the beginning. So, let’s look at what a deaerator is and what is does for you. Within water, there exists a number of disolved gases. Among these is oxygen, which can cause damage from corrosion to metal piping and walls within systems such as boilers. A deaerator helps remove these dissovled gases from the water. This is especially useful in feedwater for some boilers.

This process is completed by heating up eater to near saturation point. The deaeration system has a minimum pressure drop and minimum vent. The system then sprays the feedwater and can sometimes include flowing over multipel trays or scrubbers. This steam is then fed to the bottom of the system. Steam comes into contact with the feedwater, it is heated up to saturation temperature.

At this point, the dissolved gases are released from the boiler feedwater and vented out. Treated water fills the storage tank at the bottom. You have safe and clean water to help keep pipes and other metal surfaces safe from corrosion and rust.

Parts of the Deaeration System

There are far too many parts of any daeration system to list in this space. We have gathered just a few of the common deaerator parts you will come across in your travels.

– Relief valves are placed on deaeration system to prevent overpressure issues. Deaeration systems may have one or more relief valves depending on size and use.

– Pressure gauges allow users to monitor the steam space inside the deaeration system. Always check the operating pressure and the gauge resolution in deaerater pressure gauges.

– Control valves allow you to control water flow. This inlet water can be coming from one or multiple sources.
