Should this vent valve not be opened sufficiently the deaerator will not work properly, causing high oxygen content in the feed water going to the boilers. Should the boiler not have an oxygen content analyser a high level in the boiler chlorides may indicate the vent valve not being far enough open.

Using Gas Analyzer Readings - ratwell.c

2017-1-6 · Oxygen, measured as a percentage of the exhaust volume, reflects the amount of gas remaining in the exhaust sample after the combustion process has taken place. Ambient O 2 readings should be about 20%, reflecting the natural amount oxygen found in the air. The ideal range for vehicles without a secondary air injection system is less than 1.5%.

Combustion Fundamentals - Industrial Wiki - odesi

The oxygen needed to support combustion comes from the air that surrounds us. Air is a mixture of gases consisting mainly of about 21 percent oxygen and about 78 percent nitrogen of volume. The remaining 1 percent consists of small amounts of argon, carbon dioxide, and other gases. Even in a simple wood fire oxygen plays a part in combustion.
