Resumo: | In order to determine the potential energy of forest fuels in Pinus elliottii stands, we investigated the best season to collect fuel material considering fuel availability, moisture content, Higher Calorific Value (HCV) and immediate chemical composition, from the plots established and monitored during one year at Rio Negro Research station, Paraná state, Brazil. The year’s seasons (winter, summer, spring and autumn) were considered as experimental blocks while the diameter of the materials (AA, AB and AC) as treatments. These treatments were pre-defined in the following diameter classes: AA, in the upper layer; AB, in the intermediate layer; AC, in the lower layer, all materials up to 0,7 cm; and B, with material of 0.71 to 2.5 cm. The fuel material of all year’s seasons was collected in sub plots of 900 cm2 , weighted in the field and taken to the laboratory of the Federal University of Paraná (UFPR) to carry out the rest of analyzes including: moisture on the dry basis, fuel availability, Higher Calorific Value (HCV) and immediate chemical composition. Analyses of variance (ANOVA) and Tukey test were performed to compare the differences between seasons and material classes. Together with low moisture content and greater fuel availability, the mean test showed that, for all material classes, the winter was the best season to collect forest fuel material of Pinus elliottii stands. The results also showed that, for immediate composition and HCV, the mean class AA and B were statistically superior than the other classes. The fuel loading had a considerable density of energetic (12,275.42.105 kcal. ha-1) for bioenergy conversion and utilization. |

No delineamento experimental, as estações do ano (inverno, verão, primavera e outono) foram consideradas blocos, enquanto as seguintes classes de diâmetro do material combustível os tratamentos: AA, na camada superior; AB, na camada intermediária; AC, na camada inferior, todas com material de diâmetro até 0,7 cm; e a B, com material de 0,71 a 2,5 cm. No campo, foi determinada a massa (base úmida) do material coletado nas subparcelas de 900 cm2 e posteriormente levadas ao laboratório da Universidade Federal do Paraná (UFPR), no qual se procederam as análises referentes à umidade (base seca), Poder Calorífico Superior (PCS) e composição química imediata. Foi recorrido à análise de variância (ANOVA) e ao Teste de Tukey para comparação das épocas (blocos) e das diferentes classes de material combustível (tratamentos). Com baixo teor de umidade e maior quantidade de material disponível, observou-se pelo teste de médias, para todas as classes de material, que o inverno foi a melhor época de coleta. Para a mesma época de coleta foi possível observar pelo PCS e análise da composição química imediata que as médias das classes AA e B foram estatisticamente superiores em relação às demais. A manta apresentou densidade energética considerável (12.275,42.105 kcal.ha-1) para conversão em bioenergia. Pelos resultados do presente estudo observou-se que existe potencial para aproveitamento de resíduos florestais como fonte de energia limpa e renovávelUniversidade Federal de Santa Maria2018-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3531410.5902/1980509835314Ciência Florestal; Vol. 28 No. 4 (2018); 1640-1650Ciência Florestal; v. 28 n. 4 (2018); 1640-16501980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35314/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessMbanze, Aires AfonsoSilva, Dimas Agostinho daTetto, Alexandre FrançaPereira, José FernandoBatista, Antonio Carlos2018-12-16T20:33:04Zoai:ojs.pkp.sfu.ca:article/35314Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-12-16T20:33:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
