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 processes inside the ESP: turbulent gas flow, electrical field and discharge phenomena, particle cha

Static and dynamic back-corona characteristics

Voltage-current characteristics are a basic tool to analyse the operational conditions of an electrostatic precipitator, and to detect the onset of Back-corona, that strongly affects the collection performances. In this investigation, a laboratory set-up has been arranged, with a classical ESP wireplate configuration; both static and dynamic voltage-current characteristics have been measured and analysed with different geometries, dust characteristics, and layer thickness. Similar results hav

Electrostatic precipitator modelling: from University study to application

The need to understand variations in the performance of an electrostatic precipitator, in order to remain in compliance with the regulations whatever coal is burned, leads us to place at the disposal of the operator a user-friendly expert investigation tool based on a complete description of the phenomena involved during the dust collection.

The code used, obtained from much work in universities, calculates the dust collection efficiency per size class, as a function of the inlet velo
