Abstract

Abstract: In this study, the emissions of three different generations of firewood stoves were characterized to test their sustainability with this new problematic. Organic Carbon (OC) and Elemental Carbon (EC) emissions were particularly targeted. After an investigation of the OC/EC measurement method, a specific protocol was developed, validated and optimized in order to measure OC/EC from direct samplings in the flue gas, without diluting or cooling systems. Carbon monoxide (CO), Total Suspended Particles (TSP) and Total Hydrocarbon (THC) emissions were followed too. To go further in the characterization and in the differentiation of the particles emitted from each kind of stoves, a Field Emission Gun Scanning Electron Microscope (FEG SEM) was used. The medium generation emitted 40% less mass of OC than the previous one. Concerning the new generation, emissions were reduced in mass about 98% for the EC and 40% for the OC compared to the old generation. Graphical abstract: Highlights: An addition of sucrose on filters improve the OC/EC analysis accuracy. The OC emissions are directly linked with the VOC emissions. The technology of a stove induce a specific composition in carbon of the particles. The new generation of stove emits much less pollutants than the older generation.
