What is a common result of high levels of O and CO2 in condensate lines?

High levels of oxygen (O) and carbon dioxide (CO2) in condensate lines can lead to corrosion, which is the correct answer. In a steam system, condensate should ideally be free of contaminants. However, the presence of oxygen, when combined with moisture, can accelerate the corrosion process in metal components. Oxygen is a reactive element that can cause pitting and uniform corrosion in steel pipes, leading to reduced structural integrity over time.

Additionally, carbon dioxide can dissolve in water to form carbonic acid, which further contributes to acidic conditions that promote corrosion. This is particularly detrimental to boiler systems and piping, as it creates an environment where metal deterioration occurs more rapidly. Ensuring that condensate lines are treated and monitored for these gases is crucial for maintaining the integrity and longevity of the system, thus making corrosion a common result of elevated levels of oxygen and carbon dioxide.

While increased pressure, reduced flow, and boiler scaling may occasionally be issues in steam systems, they are not direct results of high O and CO2 levels in condensate lines in the same way that corrosion is.
