Comparison of electrostatic fine powder coating and coarse powder coating by numerical simulations

Characteristics and the behavior in electrostatic precipitators of high-alumina coal fly ash from the Jungar power plant, Inner Mongolia, China

“…As compared to a mechanical ash separator such as gravitational settling and cyclone, ESP achieves high overall mass collection efficiency, which is usually above 99% [5,6]. However, in China, there has been a decrease in the collection efficiency of ESPs in some power plants (Jungar 96.9%, Tuoketuo 96.7%) after burning Jungar high-alumina coal in Inner Mongolia.…”

Characterization of particle size evolution of the deposited layer during electrostatic powder coating processes

“…On the other hand, Barmuta et al [18] observed that the substrate tends to collect small particles, and they attributed this phenomenon to the effect of electroseparation during powder coating processes. Many other earlier studies [19][20][21][22][23][24][25][26] widely investigated particle behaviors in charging and deposition efficiency. Unfortunately, few were conducted to examine the size evolution in the deposited layer during powder coating processes.…”

Integrated process and product analysis: A multiscale approach to paint spray

“…Although air flow, electric field, and particle trajectories were investigated in detail, the film formation process was not studied. Shah et al presented numerical simulations for electrostatic powder coating 24. Gas flow, electric field, and particle trajectories models were utilized to investigate the effects of operational conditions (e.g., powder spray rate, electrostatic voltage, and air flow rate) and particle size change on coating quality (i.e., coating thickness uniformity) and transfer efficiency.…”
