Charging and Collection of Submicron Particles in Two-Stage Parallel-Plate Electrostatic Precipitators

Collection of Submicron Particles in Electrostatic Precipitators: Influence of Ehd Agitation and of Particles Disintegration

The paper focuses on two particular phenomena which contribute to the poor collection efficiency of fine particles (from ~ 0.1 μm to ~ 2 μm) by electrostatic precipitators (ESPs). Firstly, the influence of turbulence on collection rate is considered as well as the fact that the charged fine particles are expected to give the main contribution in the generation of small eddies in ESPs. Experimen...

Collection of fine particles in electrostatic precipitators : influence of EHD induced agitation and of particles disintegration

The paper focuses on two particular phenomena which contribute to the poor collection efficiency of fine particles (from ~ 0.1 μm to ~ 2 μm) by electrostatic precipitators (ESPs). After considerations on the influence of turbulence which tends to decrease the collection rate, a conjecture is recalled on the action of the charged fine particles which is expected to give the main contribution in ...

An Analysis on the Velocity of Dust Particles in the Plate-type Electrostatic Precipitators Used in Thermoelectric Power Plants

Experimental data collected from different plate-type electrostatic precipitators used in a thermoelectric power plant has been analyzed. The following parameters were considered: the collection efficiency, average migration velocity of dust particles, velocity distribution of the gas in the input and output channels of precipitators. The average migration velocity of dust particles can be esti...

Next Generation Wet Electrostatic Precipitators

Multi-pollutant control technologies will become more important in the future. This new membrane wet electrostatic precipitator (WESP) system is ideally suited to, and very cost effective for, removing PM2.5, SO3 and Hg after limestone wet flue gas desulphurization (WFGD) scrubbers in the utility industry. Several coal-fired utilities have been experiencing increased SO3 emissions from their ex...
