All About Deaerators

Steam boilers do exactly as their name implies, they produce steam; however, may factors must be considered and managed to do this, including corrosion, scale, water minimization, fuel efficiency, safety, and Total Cost of Operation. Boiler feedwater often contains dissolved gases, such as oxygen, carbon dioxide, and ammonia. These dissolved gases are problematic for the boiler system because they may cause corrosion, leading to equipment failures (e.g., carbon dioxide can form carbonic acid in boiler condensate, lowering the pH, and corroding the condensate piping). To minimize corrosion, the dissolved gases must be removed or neutralized. This can be achieved through the use of deaerators, which work to remove such dissolved gases to low levels reducing the amount of follow-up neutralization required (e.g., sulfite-based oxygen scavenging).

What is PPM?

The phrase “Part Per Million” is a term we use to describe very small amounts of something in a much larger amount of something else. Here are some examples of one part of something in a million parts:

Guidelines for Inspecting a Boiler

The purpose of a boiler inspection is to provide assurance of equipment integrity to minimize safety issues with operating a pressure vessel. A minimal frequency is established by law and the Insurance Company that is covering customer liability in case of any operational failures. It has a useful secondary function of acting as an early warning of potential problems and determine the water treatment program’s effectiveness.

An internal boiler waterside inspection consists of all waterside areas of the vessel (e.g., steam and water areas, blowdown lines, feedwater connections, and low water safety devises) as well as dearators, superheaters, economizers, and blowdown heat exchangers. If possible, this inspection...

How Blended Water Supplies Impact Water Treatment

Not All Water Supplies are the Same

The source(s) of water supplied to cooling towers, boilers, and processes may vary greatly daily or even hourly.  The impact this has on water systems must be closely monitored to avoid scale, deposits, corrosion, inefficient water usage, and other negative impacts on operational costs.

How Often Should I Test My Water?

Chem-Aqua representatives are frequently asked, “How often do I need to test my water?”  The answer to this question is as varied as the systems that Chem-Aqua treats.  There are a number of factors that go into determining the “best practice” for each facility.  Typically, these factors are:
