Capture of submicrometer particles in a pressurized electrostatic precipitator

Novel Wet Electrostatic Precipitator for Sub - Micron Particles

The waste incineration plants, power generation utility, chemical industry, etc. require the efficient removal of submicrometer particles from raw gases. Wet electrostatic precipitators (WESP) are the most effective control device for fine aerosol from the humid raw gases. They use less energy than mechanical collection devices, have no moving parts to wear, their maintenance costs are lower, p...

Measurement and capture of fine and ultrafine particles from a pilot-scale pulverized coal combustor with an electrostatic precipitator.

Experiments were carried out in a pilot-scale pulverized coal combustor at the Energy and Environmental Research Center (EERC) burning a Powder River Basin (PRB) subbituminous coal. A scanning mobility particle sizer (SMPS) and an electrical low-pressure impactor (ELPI) were used to measure the particle size distributions (PSDs) in the range of 17 nm to 10 microm at the inlet and outlet of the ...

Local Deposition of Particles in a Laboratory-Scale Electrostatic Precipitator with Barbed Discharge Electrodes

The precipitation of particles in an electrostatic precipitator (ESP) results in striking dust patterns at the collecting electrodes, strongly depending on forces of the electrohydrodynamic (EHD) field in the duct. Due to precipitator geometry, electrical operation status, and process parameters, areas of high and low dust density are visible. Since latest results show a direct correlation of p...

Role of Electrostatic Precipitator in Industry

Electrostatic Precipitators (ESP) are most important device used to control the pollution by collecting dust particles present on flue gases. In power plants, Coal used in Indian thermal power stations is of inferior grade, at power plant flue gas is often treated with a series of chemical process and scrubbers, having low calorific value (3500-4500)kcal/kg and high ash content due to drift ori...
