    Deaerator - Wikipedia

    2019-5-9 · A deaerator is a device that removes oxygen and other dissolved gases from water, such as feedwater for steam-generating boilers. Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (rust). Dissolved carbon dioxide combines with water to

    2019-5-24 · The deaerators are normally used in any chemical process industry or in power plants where the boiler is used for the production of steam from the boiler feed water. The heating deaeration process is the separation process done by using mechanical equipment that has been designed in such a way that is used for the work process as desired.

    2010-1-1 · Every boiler plant has a deaerator that generally gets little or no attention until it jeopardizing the entire steam system. These incidents can be expensive to correct and affect the integrity of other critical auxiliary equipment as well as the careers of those charged with technical oversight of utility systems. Deaerators are large, insulated tank-car-shaped pressure vessels.

    While oxygen and carbon dioxide could be removed by the addition of scavenging chemicals to the feedwater alone, this practice is extremely costly in all but the smallest plants. Generally speaking, plants generating in excess of 10,000 lb/hr of steam can justify the installation of a Deaerator.

    This feature also raises the feedwater temperature, thus requiring less boiler fuel to convert the feedwater to usable steam. Boiler tubes, condensate lines, and process piping have a much longer useful life by eliminating the pitting action of untreated water. This advantage alone justifies the cost of an “OXYMISER” deaerator. How Does It

    A remote deaerator is similar in design to an integral deaerator, except it is not connected to a low-pressure evaporator system of the HRSG. Without a heating steam source of its own, a remote deaerator will rely on pegging steam from the HRSG or another source to …
