Pesquisa do estado de Minas Gerais (FAPEMIG) / Neste estudo foi caracterizado o lodo proveniente de ETE situada em Patos de Minas/MG atrav?s da quantifica??o sua capacidade energ?tica, e avalia??o sua viabilidade no acionamento de usinas termoel?tricas. Para isto foram determinados os teores de metais, areia, mat?ria org?nica e inorg?nica, pH, carbono org?nico total (COT) al?m da an?lise imediata do material. O comportamento t?rmico foi analisado atrav?s de TGA, DTA, DSC e Calor de combust?o. Foram analisadas quatro amostras, sendo Lodo sem tratamento coletado em ?poca seca (LSTS), Lodo sem areia coletado em ?poca seca (LSAS), Lodo sem tratamento coletado em ?poca chuvosa (LSTC) e Lodo sem areia coletado em ?poca chuvosa (LSAC). Os resultados encontrados apontam para maior viabilidade energ?tica da amostra LSAS, devido ? sua baixa umidade (8,7802 %), alto teor de materiais vol?teis (53,1408 %), baixo teor de cinzas (0,7283 %) e alto teor de carbono fixo (46,1308 %). O poder calor?fico encontrado nesta foi de 9.752 J/g, sendo este equiparado ao de madeiras como Ac?cia-Negra e Eucalipto. Desta forma os resultados confirmam a viabilidade de utiliza??o do lodo como combust?vel ao se observar que as caracter?sticas t?rmicas s?o equiparadas ? diversas biomassas energ?ticas. / Disserta??o (Mestrado) ? Programa de P?s-gradua??o em Biocombust?veis, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2018. / In this work was characterized the sludge from ETS situated in Patos de Minas city / MG by quantifying its energetic content and evaluating its feasibility in the operating of thermoelectric power plants. For this, the contents of metals, sand, organic and inorganic matter, pH, total organic carbon (TOC) and the energetic content of the material were determined. The thermal behavior was analyzed by TGA, DTA, DSC and heat of combustion. Four samples were analyzed: sludge without treatment collected in dry season (LSTS), sludge without sand collected in dry season (LSAS), sludge without treatment collected in rainy season (LSTC) and sludge without sand collected in rainy season (LSAC). The results suggest that the LSAS sample was more energetic efficient due to its low moisture content (8.7802 %), high content of volatile materials (53.1408 %), low ash content (0.7283 %) and high carbon content (46.1308 %). The calorific power was found to be around of 9,752 J / g, being this one very closed to the wood as Acacia-Negra and Eucalipto. In this way, the results confirm the feasibility of using the sludge as fuel when observing that the thermal characteristics are assimilated to the different energy biomasses.
