Deaerators are useful because they remove the gases that attach to the metallic components of the steam system and cause deaegator by forming oxides, or rust.

Both oxygen and carbon dioxide are responsible for corrosion, which is why the majority of boiler deaerators are capable of removing oxygen to levels that virtually eliminate carbon dioxide. There are two main types of boiler deaerators: The tray type features a vertical section that is domed and mounted to the top of a horizontal tank that stores the water for the boiler.

The spray type is a cylindrical tank that both deaerates the feed water and stores it. Before you can understand how a boiler deearator works, you need to learn more about boiler deaerators themselves. We explore the following topics to help you gain a better understanding of the process a boiler deaerator uses to remove dissolved gas from water to protect the boiler system itself from corroding:.

What is a Boiler Deaerator and How Does It Operate? – MPC

Continue reading to learn more about the ways in which water deaerators operate and how to ensure your deaerator is functioning efficiently. Boiler deaerators must condition feed water to remove dissolved gases before it can be used in the boiler system and eventually corrode it. In many cases, feed water is cold and contains several dissolved gases, with oxygen leading the pack.

Regardless of the type of boiler deaerator, each functions generally in the same way. When water passes from the feed water tank into the boiler deaerator, it enters through the inlet water connection. The water flows through a heating and venting section that is filled with steam.

The water temperature rises, which releases most of the undissolved gases in it including oxygen and carbon dioxide. When the water flows through the deaerator, it passes to the scrubber section.

It is in this section where the last step of deaeration takes place because it scrubs the water with steam that is free of oxygen. Then, the steam goes through a stainless steel spray valve that breaks down the high-velocity steam into a fine mist. The deaerated water flows over to the storage compartment and is ready for use by the boiler while the gases vent to the atmosphere.

By virtually eliminating the amount of dissolved oxygen and carbon dioxide in the feed water, boiler deaerators help lower operating costs and improve steam quality for facilities.

However, some conditions warrant placing oxygen scavengers in other locations. One commonly used oxygen scavenger is sodium sulfite. Some higher pressure boilers, however, cause the sulfite to decompose and enter the steam, which may pose a hazard in condensate systems and condensing steam turbines.

Boiler deaerators feature a mechanical design that enables them to use steam pressure and temperature to condition feed water. When the temperatures, pressure, and dissolved oxygen levels are within design limits, boiler deaerators operate at maximum efficiency. It is important to check the temperature and pressure daily and log the data into a database to conduct trend analysis. Should any fluctuations be present, you should schedule maintenance for the deaerator controls. Physical inspections of deaerators also show whether an internal component failed.

Boiler deaerators serve a critical role in protecting steam systems from corrosion. It is important to understand how they operate and how to eliminate dissolved oxygen in the deaerator with the assistance of oxygen scavengers in order to determine whether your boiler deaerator is ciletype efficiently.
