Abstract in another language

Wood-log fuelled fireplaces in domestic households are widespread. Biomass combustion saves fossil resources, but emissions from such stoves might affect human health. Especially fine dust emissions appear carcinogenic. Automatically controlled combustion might be a solution for future wood-use in heat generation. For that purpose, sensors installed in the flue gas should give continuous and reliable insights concerning gaseous and particulate matter emissions. Resistive particle sensors are known from automotive applications. Typically, they are operated discontinuously: As long as soot deposits on the electrodes, an increasing current signal can be measured. After a certain time, the sensor has to be regenerated at higher temperatures (soot oxidation). Figure 1 shows an initial test with a simple soot sensor (own development, details in [1-4]), installed in the flue gas of a single-room fireplace (LEDA Unica, Germany). Several slopes could be evaluated and correlated with data from a continuous particle analysis (DMS500, CAMBUSTION) – here the product of the “Aerosol Mode Concentration” (i.e. the particle number concentration, PNC) and the “Aerosol Mode” (i.e. count media diameter, CMD).
