Impedance spectroscopy characterization of an interdigital structure for continuous particle measurements in wood-driven heating systems
In the course of the climate change and increased focus on CO<sub>2</sub>-neutral energy sources, the use of wood-driven small heating systems (SHS) becomes more important. But, their contribution to air pollution, especially particulate matter, is about as high as the emissions from car...

description |
In the course of the climate change and increased focus on CO<sub>2</sub>-neutral
energy sources, the use of wood-driven small heating systems (SHS) becomes
more important. But, their contribution to air pollution, especially
particulate matter, is about as high as the emissions from car engines. The
specific formation of harmful substances in wood fires and possible
countermeasures by continuously operating sensor and control systems are
covered.
<br><br>
Impedance spectra of interdigital electrode (IDE) structures are taken before
and after mounting in wood-driven SHS to get information about the particles
in the exhaust stream. It appears that the capacitive parts of the impedance
spectra at a fixed frequency are appropriate for a fast signal evaluation.
The good correlation with established offline measuring methods is discussed
and the capability of thermal regeneration is demonstrated. The offline
measurements of this work shall give the experimental basis for the
development of online measurements in order to control the particle emissions
of wood-driven SHS. |
