WebHeat can be recovered from Corrosive and Fouled flue gas. In the industry, significant amounts of energy are lost via the stack. Stack losses are concentrated and therefore a great place to recover heat. However, acid dew point corrosion has been stopping operators from recovering this heat. But not any longer! WebAug 1, 2024 · 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 …

WebNov 12, 2024 · The flue gases normally flow out of the house and disperse into the atmosphere. However, sometimes problems arise, and the flue gases spill back into the house. Potential Causes. Anything that interferes with the flow of flue gases out of the house can cause spillage. The following are some potential causes. Improper Vent … WebIs flue gas corrosive? The corrosiveness of flue gas is the main reason why the energy efficiency of furnaces, fired heaters and steam boilers remains poor. Flue gas originating from sulphur containing fuel becomes corrosive below a temperature of approximately 150C (acid dew point corrosion). marisa minetti divorcio
