Scientists at CSIRO's divisions of Coal and Energy Technology and Applied Physics are investigating the workings and design of the electrostatic precipitator, one of the means of reducing industrial flue emissions. The team has also found that pulsed power supply improves dust collection in the precipitator. Another project at the Division of Coal and Energy Technology involves the commercial development of a process that recycles transformer oil. The $2.3 million project aims to develop a simple economic process that can be used at remote power stations and electricity substations.
