As the 4thlargest global primary energy carrier following fossil fuels (coal, oil and natural gas), biomass is the most abundant renewable energy source on earth. Among all the biomass conversion technologies, the direct burning of biomass for heat and power generation is the most common and cost-effective route to turn biomass into energy. Natural wood biomass is widely used as an alternative to fossil fuels to reduce atmospheric emissions from heat and power generation in the UK, France and the rest of the world. Meanwhile, black pellets are recently produced from various woody biomass or agricultural residues through a thermal process, called torrefaction. Black pellets are regarded as high-grade solid biofuels with stable, homogeneous and greater energy density and calorific value than the original biomass. It is believed that torrefied biomass offers a cost-effective route to significantly increase the use of biomass as a renewable energy source and at the same time to lower greenhouse gas and particulate emissions from heat and power generation.However, there are very limited systematic and comprehensive evaluations of the combustion characteristics and environmental benefits of these two types of biomass fuels.The aim of this thesis is to quantify the combustion characteristics and associated pollutant emissions of natural wood pellets. To achieve this goal, A modified 10 kW boiler was used as the burner in our research. The characterization of the combustion of natural wood pellets is carried out using advanced equipment (measurement of gaseous emissions by analyzers and study of particulate emissions by LII and SMPS). In addition, a calibration method has been improved to directly deduce the soot volume fraction from the LII signal using the absolute radiance emitted from a light source having black body. In parallel, SMPS technology is also used to measure the particle size distribution of particulate matter emissions. Emissions of gaseous and particulate pollutants were studied for two conditions, with and without secondary air.

Among all the biomass conversion technologies, the direct burning of biomass for heat and power generation is the most common and cost-effective route to turn biomass into energy. Natural wood biomass is widely used as an alternative to fossil fuels to reduce atmospheric emissions from heat and power generation in the UK, France and the rest of the world. Meanwhile, black pellets are recently produced from various woody biomass or agricultural residues through a thermal process, called torrefaction. Black pellets are regarded as high-grade solid biofuels with stable, homogeneous and greater energy density and calorific value than the original biomass. It is believed that torrefied biomass offers a cost-effective route to significantly increase the use of biomass as a renewable energy source and at the same time to lower greenhouse gas and particulate emissions from heat and power generation.However, there are very limited systematic and comprehensive evaluations of the combustion characteristics and environmental benefits of these two types of biomass fuels.The aim of this thesis is to quantify the combustion characteristics and associated pollutant emissions of natural wood pellets.

520 3 $a En tant que 4èmevecteur mondial d'énergie primaire après les combustibles fossiles (charbon, pétrole et gaz naturel), la biomasse est la source d'énergie renouvelable la plus abondante sur terre. Parmi toutes les technologies de conversion de la biomasse, la combustion directe de la biomasse pour la production de chaleur et d'électricité est la voie la plus courante et la plus rentable pour transformer la biomasse en énergie. La biomasse de bois naturel est largement utilisée comme alternative aux combustibles fossiles pour réduire les émissions atmosphériques provenant de la production de chaleur et d'électricité au RoyaumeUni, en France et dans le reste du monde. Pendant ce temps, des granulés noirs sont récemment produits à partir de diverses biomasses ligneuses ou de résidus agricoles grâce à un procédé thermique, appelé torréfaction. Les granulés noirs sont considérés comme des biocombustibles solides de haute qualité avec une densité énergétique et une valeur calorifique stables, homogènes et supérieures à celles de la biomasse d'origine. On pense que la biomasse torréfiée offre une voie rentable pour augmenter considérablement l'utilisation de la biomasse comme source d'énergie renouvelable et en même temps pour réduire les émissions de gaz à effet de serre et de particules provenant de la production de chaleur et d'électricité.Cependant, il existe très peu d'évaluations systématiques et complètes des caractéristiques de combustion et des avantages environnementaux de ces deux types de biocombustibles.Dans le cadre de ce travail de thèse, nous visons à quantifier les caractéristiques de combustion et les émissions polluantes associées des granulés de bois naturel. Pour atteindre cet objectif, une chaudière modifiée de 10 kW sera utilisée comme brûleur dans nos recherches. La caractérisation de la combustion des granulés de bois naturel est réalisée à l'aide d'équipements avancés (mesure des émissions gazeuses par analyseurs et étude des émissions particulaires par LII et SMPS). De plus, une méthode d'étalonnage a été améliorée pour déduire directement la fraction volumique de suie du signal LII en utilisant la luminance absolue émise par une source lumineuse à corps noir. En parallèle, la technologie SMPS est également utilisée pour mesurer la distribution granulométrique des particules émissions. Les émissions de polluants gazeux et particulaires ont été étudiées pour deux conditions, avec et sans air secondaire.
