Some Aspects of Electrostatic Precipitator Research in Australia

Abstract

In Australia, research and development into electrostatic precipitator performance has been taking place, mainly, but not wholly, in relation to the electric power utility industry. Special interest has centered around back ioniza-tion resulting from the high resistivity fly ash prevalent amongst the low sulfur coals found there. Work has proceeded on full scale, pilot scale, and bench scale apparatus. Resistivity, adhesivity, and the permittivity of fly ash has been studied. Back ionization has been mitigated by both gas-conditioning and special energization.
