Análise energética da serragem utilizada nos fornos de queima de cerâmica vermelha

Abstract

The ceramic material is any kind of inorganic material or chemical product, nonmetallic, generally obtained after heat treatment at elevated temperatures. During its production process, the sub-stage of burning is the most costly, being responsible by 34% of all production costs, given the fuel needed to supply the kilns. Among the energy inputs used in the furnaces, sawdust coming from wood residues stands out for its calorific potential and its ease of obtaining. Thus, the present work carried out the energy analysis of sawdust used in red ceramic burning furnaces. For that, it was necessary to apply an economic questionnaire with the purpose of check question involving the production and treatments previously performed on energy inputs. Subsequently, the fuel material, wood sawdust, was collected directly from the factory, which underwent several tests, such as sawing energy analysis and immediate chemical analysis, based on ASTM D5865-13 and ASTM 1762. Having found the higher, lower and gross heating value in the order of 3424.44 kcal / kg, 2781.88 kcal / kg and 1608.81 kcal / kg, respectively. Finally, a comparative analysis was made with simulations of samples with lower moisture and inorganic material content, with an increase of 127% in energy power for sawdust under ideal conditions.
