In terms of their ecological balance, wood-fired heating systems offer a virtually closed CO2 cycle if the firewood comes from sustainable forests without long transport routes. However, they also significantly contribute to hazardous particulate emissions in cities. The BINE-Projektinfo brochure "Clean heating with wood" (06/2016) presents a new electrostatic particle separator that is especially designed for wood chip and wood log boilers with thermal outputs between 50 and 200 kW. The method is suitable for both new boilers and for retrofitting existing systems.
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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
