In common terminology in the field of coal combustion, the term “dew point corrosion” is synonymously used with sulphuric acid dew point corrosion. This clear correlation has to do with the chemistry of coal as a fuel. If reference is made to the dew point of water, the “water dew point” is expressly referred to. These common references to dew points and to sulphuric acid as the cause ...

Controlling the dew point of natural gas - DigitalRefining

However, this article excludes topics on acid gas removal and focuses on controlling both the water dew point (WDP) and hydrocarbon dew point (HDP) of natural gas with no or insignificant contents of acid gas. To avoid condensation of heavy components when the gas pressure reduces in the delivery system, the HDP of natural gas also needs to be reduced as necessary. Condensation of heavy ...

Dew point - Wikipedia

The dew point is the temperature to which air must be cooled to become saturated with water vapor. When cooled further, the airborne water vapor will condense to form liquid water . When air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface. When the temperature is below the freezing point of water, the dew point is called the ...

Dew Point Calculator

Dew point is defined as the temperature at which a given volume of air at a certain atmospheric pressure is saturated with water vapor, causing condensation and the formation of dew. Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher ...

Consequently, dew points are raised. With any type of fuel, corrosion and fouling potentials rapidly increase below gas temperatures of 140 degrees F (60 degrees C), which is the typical water dew point for flue gases. Cold-end corrosion and deposition are usually much less severe in coal-fired boilers than in oil-fired units. Usually, coal ash ...
