A Numerical Simulation for Predicting Influence of Flow Pattern in Electrostatic Precipitator on Exit Re-entrainment Loss
The electrostatic precipitator (ESP) numerical model developed by Author does a better job of qualitatively predicting influence of skew gas distribution in ESP upon performance. The results show that the higher efficiencies can be achieved by using some special non-uniform inlet & outlet gas distribution than that of uniform gas distribution and the re-entrainment of falling dust results in the dust load in the lower zone of a precipitator increasing compared to the upper zone as flow progresses through a precipitator. In this paper, the numerical model is applied to determine exit re-entrainment loss response to the variations in gas distributions across the full scale ESP entrance and exit. It examined how skew gas distribution affects re-entrainment loss and gives a physical explana-tion for the lower re-entrainment loss or higher efficiency with controlled using some special non-uniform inlet and outlet gas distributions.
