    Aug 01, 2020 Acid dew-point (ADP) is the temperature at which the acid vapor, normally means sulfuric acid (H 2 SO 4 ), in flue gas begins to condense. Acid condensation can result in low-temperature corrosion (LTC), which can threaten the safety of boilers. An exhaust temperature higher than ADP can relieve LTC, however, result in a low thermal efficiency.

    The dew point usually limits the practical lower temperature of the flue gas to 300 to 350/sup 0/F. If the temperature of the equipment in contact with the gas is below the dew point, moisture and acid, generally sulfurous or sulfuric acid, can condense and the exposed metal surface of the equipment deteriorates rapidly due to corrosion.

    For hydrochloric acid, the dew-point may be as low as 130 o F. While the precise dew-point for sulfuric acid depends on the sulfur-trioxide concentration, at 10 parts per million sulfur trioxide in the flue gas, the dew-point is 280 o F. Dew-point corrosion is exacerbated in coal-fired boilers by the presence of …
