As the first stage of a research programme aimed at improving the effi
ciency of the electrostatic precipitators, PIXE and RES analyses using
the Oxford Scanning Proton Microprobe have been carried out for about
one hundred fly-ash particles collected at the inlet of the electrost
atic precipitators of a coal-fired power plant. These show that partic
les can be grouped into several classes according to matrix compositio
n and trace element composition.
