• ### Acid Dew Point Calculation - Student - Cheresources.com

Dec 09, 2011 · Td=1000/ {3.9526 - 0.1863*ln (PH2O) + 0.000867*ln (PSO2) - 0.00091*ln (PH2O*PSO2)} Pressures (P) in the equation is given in mm Hg. I am planning to use the equation above to find the flue gas outlet temperature from waste heat boiler ( above the acid dew point ) . Initially, I used the online acid dew point calculator and obtained a value of 125 degree Celsius ( seems reasonable) .

Aug 01, 2017 · Specifically, the acid dew point increases from 116.48 °C to 156.44 °C as the content of sulfuric acid vapor increases in the range of 1–50 ppm. On the other hand, the acid dew point increases from 123.29 °C to 135.61 °C with the content of water vapor increasing from 4% to 16%. Thus, the effect of sulfuric acid vapor content on acid dew point is more significant than that of water vapor in the …

• ### Low Temperature Corrosion in Boiler and Its Prevention

The limits of detection of an Acid Dewpoint Temperature (ADT) sensor is set by the time taken to form a measurable film of sulphuric acid on the sensor. At very low concentrations, the film forms slowly. A lot of patience is needed when measuring ADT below 130 °C (266 °F), and the minimum measurable ADT is around 125 °C (257 °F).

A significant amount of waste heat in flue gases remains untapped due to the limited applicability of metal heat exchangers under conditions where acid dew point corrosion can occur. The HeatMatrix polymer heat exchanger overcomes this limitation and enables energy savings by up to 5% in combustion processes and even up to 25% on dryers.
