What is the approximate dew point temperature at which water vapor from natural gas combustion condenses?

The approximate dew point temperature at which water vapor from natural gas combustion condenses typically falls around 130 degrees Fahrenheit. At this temperature, the water vapor in the exhaust gas cools to the point where it condenses into liquid water.

Understanding the concept of dew point is essential in the context of natural gas combustion. When natural gas is burned, the combustion process generates water vapor as a byproduct. If the temperature of the flue gases falls below the dew point, this water vapor begins to condense, which can lead to moisture-related issues in combustion systems such as corrosion, material degradation, and operational efficiency problems.

The specific temperature can vary depending on the composition of the gas, combustion conditions, and ambient temperatures. However, many scenarios involving typical natural gas combustion suggest that 130 degrees Fahrenheit is a reasonable estimate for this critical threshold, as temperatures significantly higher or lower would not align with standard combustion processes and their resultant water vapor characteristics.
