The design of electrostatic precipitators by use of physical models

This paper describes how physical models can be successfully employed in the design of Electrostatic Precipitators (ESP). The development of the computational power of personal computers has made possible the development of mathematical models of complex systems, like ESP, that can be used at relatively low cost. These mathematical models simulate the non linear coupling of the different physical ...

CFD modelling of electrohydrodynamic gas flow in an electrostatic precipitator

Modelling of the flow velocity fields for electrohydrodynamic flow in a wire-to-plate type electrostatic precipitator was achieved. From calculations for the flow employing different flow models, the Chen-Kim k − ε turbulent model appeared to be the most appropriate choice to obtain a quantitative image of the resulting mean flow field and downstream wake flow of the rear wire, although this was ...

Suppression of particle deposition onto downstream wall in an AC Electrostatic Precipitator with neutralisation

Electrostatic Precipitators (ESPs) are used to decontaminate polluted environment around the tunnels. A conventional ESP has high collection efficiency but still has a problem in that its downstream walls are polluted due to particle deposition. The experiments carried out in this study have focused on how the particle deposition can be prevented by neutralising the gases. The collection ...

Precipitator Solves Dryer Problem

Plum Creek Manufacturing, Columbia Falls, Montana, installed a PPC Industries electrostatic precipitator to solve a direct fired dryer dust plugging problem. The electrostatic precipitator was installed in a very congested area and the project had to be done so the dryer was off-line a minimal amount of time. Plum Creek personnel relocated existing equipment, poured concrete footings, ran all of ...

Controlling Stack Emissions in the Wood Products Industry & Wood Fired Boilers

Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

Controlling acid gas mists

Gas cleaning New and strict pollution regulations in metallurgical plants worldwide are restricting particulate and acid gas emissions to extremely low levels. Because of that, sulphuric acid plants are being installed to remove and utilise S02 in gases resulting from the roasting of sulphide ores, smelting of ores, and burning or regeneration of spent acid or acid sludge from petroleum ...

CCS vs. Electrostatic Precipitators for Abrasives, Ceramics, Non-Soluble PM2.5, Submicron Particulate

Manufacturing Processes. Applications where conventional equipment is very inefficient or very expensive to operate and maintain provides an opportunity for the Cloud Chamber Scrubber (CCS) to showcase its unique capabilities. Abrasives manufacturing is a typical example. CCS Cloud Chamber technology was chosen by Saint-Gobain Advanced Ceramics Corp. (formerly Carborundum Corp.) for the ...

Innovative Dryer and Emission Control System at a Particleboard Installation

In 1989, Bohemia Corporation installed a new primary drying system and also air pollution control equipment at their particleboard plant in Eugene, Oregon. The drying system was composed of a Westec America triple-pass rotary drum dryer fired by a Coen sanderdust burner. The primary and secondary particulate collectors installed were also of a Westec America design. The tertiary air pollution ...

Efficient cyclone systems for fine particle collection in the pharmaceutical industry

The optimized design of gas cyclones is of particular relevance for the recovery of highly valuable products, such as in the production of active pharmaceutical ingredients (API) through drying systems such as Spray or Fluid Bed Drying (Shoyele et al., 2006). . Traditionally, these have been captured with reverse flow gas cyclones, but fine and low density particles remain difficult to capture ...

Thirty Years of Satisfactory Fluid Bed Sludge Incineration - The Northwest Bergen County Utilities Authority Experience

ABSTRACT Fluid bed incineration has been used as a sludge disposal method at the Northwest Bergen County Utilities Authority since 1969 when the first incineration unit was installed. In 2000, the third generation plant became operational. Over this period, environmental regulations have changed, as have the State mandated air pollution control devices. Since the State mandated a wet ...
