Objective:
In rural areas of Tunisia, the average wood consumption per household and per year is between 1.8 and 5.9 tones. The highest consumption was noted in the forest regions of Sejnane, Boussalem and Jendouba. Results show that traditional bread baking represents 60 to 70% of the percentage of wood consumed in households. With a view to satisfying the increasingly growing needs for firewood and charcoal in rural areas, we have initiated a selection research program oriented towards more intensive wood production including wood that can be used for energy purposes. In this work, we propose to compare the energy performance of 11 species of Eucalyptus.
Context:
The biomass produced by the Eucalyptus trees is used in the bioenergy field. The experimental material consists of wood taken from 11 species of Eucalyptus planted in the arboretum of Choucha. These species are E citriodora, E maculata, E paniculata, E astringens, E pileata, E robusta, E striaticalyx, E botryoides, E alba, E rudis and E sideroxylon. To evaluate the energy performances of the studied species, various parameters were selected: the higher calorific value (HCV), the degree of humidity and the basal density of the wood, the rates of gases released during combustion.
