Burning wood with 90% less particulate matter
A high voltage electrode electrically charges the particulates in the flue gas. The charged particles can then be electrostatically separated. © CCA - Carola Clean Air GmbH
New method for wood chip and wood log boilers
The fine dust filter is positioned at a point before the flue gas enters the chimney. The gas flows through an ionization chamber and is thereby electrically charged on a high voltage electrode. In the subsequent separation chamber, the particles are deposited on grounded steel brushes.
These regularly rotate across scraping edges, which causes the adhering particulate matter to drop into an ash pan. This method has the advantage that it is a dry process that can filter out up to 90% of the particles. The developers have tested the new separator for more than 30,000 hours on test rigs and in field trials.
At the beginning of 2015, the 1st Federal Immission Control Ordinance tightened the fine dust limits for wood-fired heating systems in accordance with specific transitional periods. This will make it necessary to install dust separators in many wood chip and wood log boilers. Together with industrial partners, the Karlsruhe Institute of Technology (KIT) has developed the new electrostatic particle separator to market maturity.
