Particulate Number Emissions and Size Distributionat a Wood Log Stove Dependent on Measurement Position and Application of an Electrostatic Precipitator

Short Introductive summary

Particulate matter emissions from small-scale biomass combustion systems have so far been characterized gravimetrically, mainly in the context of test bench measurements. An in-depth characterization of, among other things, particle number and particle size distribution under various practical operating conditions can contribute to describe the changes that occur as the particles travel through the chimney into the environment or the influence of emission reduction measures such as an electrostatic precipitator and assess the particle toxicity more precisely. The results described here, obtained from measurements taken after a wood log stove with different operating conditions and measurement positions, can contribute to the assessment of particle emissions from biomass combustion. In addition, the study provides information for the evaluation of combustion systems and separators as well as the establishment of particle number measurements at biomass combustion systems.
