Review of flue gas acid dew-point and related low ...

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.
