The Purpose of a Deaerator

Purpose of a DeaeratorThe dictionary defines the verb “deaerated” as the act of removing air or gas from an object like a water tube type boiler. Deaerators are most often used in power plants and chemical process industries, as those places most often use steam-generating boilers.

A deaerator is hardly a common household term. Yet, for many decades deaerators have been integral as equipment used to reduce operating costs and increase efficiency in businesses that use boilers. They are available at Kansas City Deaerator Company in a number of shapes, sizes, steam pressure ratings, and capacities.

Uses of Deaerators

The most important uses of a modern deaerator are:

  • To dissolve and remove oxygen, carbon dioxide, and other unwanted gases from a boiler’s feed water before it enters the boiler.
  • To raise the feed water temperature before it goes into the boiler, making the boiler require less fuel to convert the water to steam.
  • To bolster performance and efficiency.
  • By eliminating the pitting action of untreated water, boiler tubes, condensate lines, and process piping are useful for much longer.

Types of Deaerators

While there are several different types of deaerators, tray deaerators are recommended by all reputable consulting engineers worldwide. Tray deaerators (counterflow types, not parallel downflow types) are the only deaerators approved by the Heat Exchange Institute (HEI) because they keep all gasses contained in stainless steel to protect the carbon steel vessel from corrosion. Tray counterflow deaerators are the choice where longevity and trouble free operation are required.

The deaeration process in a custom tray type deaerator from Kansas City Deaerator Company takes place in a stainless steel enclosure that eliminates any need for vessel lining or cladding, ensuring a long life with little maintenance. The company serves customers throughout the United States with deaerators, accessories, pumps, and ancillary equipment.
