Aspects of forces on charged particles in electrostatic precipitators

An electrostatic precipitator comprises a number of electrodes whose geometry, hopefully, has optimum corona generation properties. Flue gas flowing through the interelectrode space is ionised and corona currents are distributed over the earthed receiving electrode. Solid particles in the gas being charged, are accelerated to the receiving electrode where they deposit in layers. In tliis dissertation, the basic processes of gas ionisation; particle charging, collection and final disposal, are reviewed and some problem areas identified. The word "particle" in the thesis title is used in a broad sense to include both solid dust particles and ions.
