The flue gas temperature is around 200 ℃, and SO2, NOx, etc. are generated during the heating and discharging processes of asphalt and heavy oil. The dust consists of crushed stone, river sand, limestone powder, and residue from the combustion of tar and asphalt, with a high viscosity of the dust. MPPS needle felt for water and oil repellent treatment can meet the requirements of this working condition.
