Abstract
The paper reports the numerical investigation and experimental investigation of flue gas condensation and fine particle removal of an integrated technology (condenser, the same below) for industrial boiler. The average temperature drops to 159°C and velocity increases to 22m/s at the outlet of condenser. Furthermore, it is estimated that the mean flue gas condensation efficiency of the condenser reaches to 99.02% and its particle removal efficiency arrives at 94.8% on average under the identical operational conditions. As for the classification of dust removal, the volume fraction of flue ash denoted PM2.5 and PM10 decreases by 57.64% and 43% respectively. Finally, correlation between flue gas condensation and fine particle removal are positive. Therefore, the condenser can be applied to release the latent heat and reduce the emissions of fine particles. This paper can provide reference with the design, function and test of the heterogeneous condensation technology.
