Dry electrostatic precipitators (ESP)

Dry electrostatic precipitators (ESP) are used to reduce ash and other particles; also in combination with upstream dry-scrubbing (DeSOx) and downstream catalytic denitrification (SCR-DeNOx) where necessary.

DESPs are regarded as reliable and cost-effective in the combustion of wood and biomass. It is possible to simply dispose of any dry dust that has accumulated.
