Resumo: | http://dx.doi.org/10.5902/198050985743The objective of this work was to evaluate the efficiency of fire retardant in relation to the applied volume and the application period. The experiment has been realized on the Forest Fire and Nature Conservation Laboratory of the Federal University of Viçosa (UFV), in Minas Gerais, Brazil. After the solution application of 600 and 900ml/m² on five repetitions, the efficiency has been evaluated during four weeks. Parcels of 3,0 X 1,0 m have been built in a ramp with mean inclination of 27º. It has been spread 1,20kg/m² of Melinis minutiflora Beauv as burning fuel on the area. The product efficiency has been evaluated comparing the applied quantities and the application period observing the flames height, cover speed, burn intensity and burn period on the portions with and without the product. The relative air moisture and the fuel material moisture at the burn moment have been determined. The results have shown that the application period did not have influence on the product action. The mean period that the fire line took to cover the parcel with the product was, in average, seven times slower than the part without the product. The burn intensity was around eight times minor, despite the fire covered all area. The same occurred to the flames height which was three times lower than the area without the product. |

O experimento foi realizado nas dependências do Laboratório de Incêndios Florestais e de Conservação da Natureza/UFV, com aplicação da solução retardante a 600 e 900 ml/m2 e avaliada sua eficiência ao longo de quatro semanas, empregando-se cinco repetições. Parcelas de 3,0 x 1,0 m foram montadas em uma rampa com 27º de inclinação média, com o maior comprimento no sentido do aclive, utilizando como material combustível 1,20 kg/m2 de Melinis minutiflora Beauv., distribuído uniformemente sobre a parcela. A eficiência do produto foi avaliada comparando-se as quantidades aplicadas e o tempo de aplicação utilizando-se altura das chamas, velocidade, intensidade e tempo de queima, na porção com e sem o produto. Foi determinada a umidade relativa do ar e do material combustível no momento da queima. Os resultados mostraram que o tempo de aplicação não influenciou na ação do produto e que o tempo para a linha de fogo percorrer a parte da parcela com o produto foi, em média, 7 vezes mais lento que na parte sem o produto e a intensidade cerca de 8 vezes menor, apesar de o fogo percorrer toda a área. O mesmo aconteceu com a altura das chamas que foi três vezes mais baixa que na área sem o produto.Universidade Federal de Santa Maria2012-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/574310.5902/198050985743Ciência Florestal; Vol. 22 No. 2 (2012); 365-371Ciência Florestal; v. 22 n. 2 (2012); 365-3711980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5743/3511Filho, Cláudio MachadoMartins, Maria CristinaRibeiro, Guido AssunçãoLima, Gumercindo SouzaCardoso, Marco TúlioTorres, Carlos Moreira Miquelino EletoPinto, Flavia Barretoinfo:eu-repo/semantics/openAccess2014-08-26T01:10:59Zoai:ojs.pkp.sfu.ca:article/5743Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-26T01:10:59Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
