Wood combustion process: Characterization of gaseous emissions of different parts of a spruce tree by means of a gasfying wood stove

Among the renewable energy sources, woody biomass offers advantages over other traditional fossil fuels. In particular, regarding the emissions, biomass seems interesting because of its lower ash, nitrogen and sulphur content. The present work has been developed as a part of a two years project (BiQuEEn - financed by a local Foundation of Trentino region). The final goal of the project is the efficient exploitation of energy from clean renewable spontaneous biomasses in an innovative and optimized way. The aim of this section is the characterization of the gaseous emissions of the spruce, which is one of the most widespread arboreal species in Trentino-Alto Adige region, using a two staged -high efficiency- air gasifying wood stove. The combustion technology adopted confirms that gasification technology significantly limits the emission of unburned compounds.
