| contents | Evaluation of the calorific values of wastes from some tropical wood species Aurel Lunguleasa Cosmin Spirchez Octavia Zeleniuc Agrociencias Ash content wood biomass energy release calorific value tropical specie The paper aims to analyze and classified some exotic wood species from tropical Africa, on regard to calorific features, in order to view the ability of their biomass to be a solid, natural and renewable fuel. The calorific values of wood wastes of eight tropical species were determined using an oxygen bomb calorimeter. The tested specimens were conditioned at a moisture content of 10%, 20%, and 50%. The influence of moisture content on calorific value and density, heat release rate and calorific efficiency were also analyzed. The biggest high calorific value and low calorific value were obtained by Guaiac and Rose species (21200-20700 kJ/kg). Acajou had the lowest values of high calorific value and low calorific value (18929 and 18456 kJ/kg, respectively). For higher wood density (Guaiac) the higher calorific density was obtained. The moisture content of specimens had negatively influenced the calorific efficiency and rate of energy release. The ash content was below 4% with highest values for Guaiac (3,6%) and the lowest for Acajou (0,5%). The results showed that the analyzed tropical wood species had a forest calorific capacity with 23-47% higher than of European beech, thus can be considered a good potential as renewable energy resources. 2020 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48564750002 https://www.redalyc.org/journal/485/48564750002/ https://www.redalyc.org/journal/485/48564750002/html/ https://www.redalyc.org/journal/485/48564750002/48564750002.epub https://www.redalyc.org/journal/485/48564750002/movil en http://www.redalyc.org/revista.oa?id=485 Maderas.
