“…Theoretical and numerical research has been previously done on ESPs to predict the efficiency (Al-Hamouz & Abuzaid 2002;Cooperman 1971;Kocik et al 2005). In 1999, Kim & Lee (1999) did an experimental study and compared the results with theoretical models.…”

The present numerical study involves the finding of the collection efficiency of an electrostatic precipitator (ESP) using a finite volume (ANUPRAVAHA) solver for the Navier-Stokes and continuity equations, along with the Poisson's equation for electric potential and current continuity. The particle movement is simulated using a Lagrangian approach to predict the trajectory of single particles in a fluid as the result of various forces acting on the particle. The ESP model consists of three wires and three collecting plates of combined length of L placed one after another. The calculations are carried out for a wire-to-plate spacing H = 0.175 m, length of ESP L = 2.210 m and wire-to-wire spacing of 0.725 m with radius of wire R wire = 10 mm and inlet air-particle velocity of 1.2 m/s. Different electrical potentials (ϕ = 15-30 kV) are applied to the three discharge electrodes wires. It is seen that the particle collection efficiency of the ESP increases with increasing particle diameter, electrical potential and plate length for a given inlet velocity.

“…Negative corona discharge phenomena occur in a range of industrial applications, including spray painting in the automotive industry, ozone generation, and cleaning of toxic gases [6,8,11,12,14,16,26]. These applications are commonly treated using a one species model for the corona phenomenon.…”

“…In an electrostatic precipitator, which is an air cleaning device, charge that is created by ionization attaches to polluting particles which subsequently are guided towards the collecting plates [4e6, 8,11,12,14,19]. Furthermore, for the considered geometry, Alstom Power in V€ axj€ o, Sweden has performed measurements of the current density at the collector plates [4,5], which are used to validate the domain decomposition method.…”

“…These methods are very popular, especially the electrostatic precipitator (ESP). Because the smoke particles from wood combustion are in the submicron range and the concentration is variable, the most effective collection device technology is a corona discharge device or the ESP (Kalasee et al, 2003;Kocik et al, 2005;Tekasakul et al, 2006;Intra et al, 2007;Intra et al, 2010). Particle collection by this technique is advantageous because of its high collection efficiency (especially for small particles) and small pressure drop.…”

“…Although many attempts have been made to use the ESP for removal of aerosol particles from biomass combustion (Kalasee et al, 2003;Kocik et al, 2005;Tekasakul et al, 2006;Intra et al, 2007;Kalasee 2009;Intra et al, 2010), the collection efficiency and electrode cleaning mechanisms still need to be improved. Most of the devices are operated in dry condition where the collected particles can be removed by rapping or hammering.…”

A simple wire-plate electrostatic precipitator (ESP) was constructed in order to test the efficiency of collecting smoke particles from combustion of rubber-wood that is used as a source of biomass energy. The ESP contains a maximum of 15 collection plate electrodes and 20 wire electrodes per row between plates. The maximum input voltage of the Wheatstone bridge circuit using a high-voltage neon transformer was 13.5 kV (DC). The gap between plates and the distance between wires were adjustable. Results from the field test in a furnace indicate that the device could be used for a period of about one hour before cleaning the electrodes was required. The collection efficiency was decreased during the course of wood burning as the dust loading increased. Maximum efficiency was near 80% during the initial period. The distance between the collection plate electrodes had a greater influence on efficiency than the distance between the wire electrodes. The cleaning system used in this experiment was made from a row of PVC pipes to allow water to discharge radially to the plate electrodes on both sides. This system was equipped with the case of maximum collection efficiency that had a 50 mm gap between collection plate electrodes and a 64 mm distance between wire electrodes. Efficiency was increased after 120 minutes and maintained a collection efficiency of about 60%. This ESP is suitable for small and medium-sized enterprises (SMEs) to alleviate the release of detrimental chemicals such as PAHs into the atmosphere.
