    Application of Super Austenitic Stainless Steel in wet flue gas desulfurization process system. In some power plants, the coal-fired flue gas passes through the absorption tower and is discharged directly into the chimney without a flue gas heater (WGGH). This type of chimney becomes a wet chimney.
