Estimating acid dewpoints in stack gases

WebGiven a flue gas composition, its acid dew point can be predicted fairly closely. As an approximation, the sulfuric acid dew points of flue gases from the combustion of fuels in thermal power plants range from about 120 C to about … WebDew Point of Flue Gas If the total pressure of the products is assumed to be atmospheric , i.e. 101.325 kPa , then from a steam table, find T d.p = f (P water Example 3 Find the dew point of a flue gas at 150oC being exhausted out of chimney at atmospheric condition. The flue gas composition is CO 2 13%, SO 2 0.05%, O 2

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 ...
