QUALIDADE DO CARVÃO VEGETAL PRODUZIDO EM FORNO CAIEIRA NO MUNICÍPIO DE OEIRAS DO PARÁ

Abstract

Brazil is the largest consumer and producer of charcoal in the world, accounting for almost 80% of the consumption of this material by the steel industry. Although many works are produced on the energy biomass of coal, a small portion of the work is aimed at the quality of this material, where it is basically the importance, because it is from these analyzes that are established or not the recommendations for their use. products. Thus, the present work makes qualitative surveys about a charcoal produced in the municipality of Oeiras do Pará, manufactured with the Caieira system, and the wood is the product of the residue of cutting and burning culture. Analyze the quality of coal. It was held at the Forest Products Technology Laboratory located at the Federal Rural University of Amazonia, at the Belém Campus. The techniques of Drumming were used; Moisture content; Volatile Material Content; Ash content; Fixed Carbon Content. The coal from the municipality of Oeiras has a humidity of 4.88% (± 1.16); volatile materials content 26.83% (± 4.43); fixed carbon content 68.80% (± 4.65); ash content 4.38% (± 0.22), calorific value of 6.805 (± 225.9). Being significant physicochemical differences when compared to charcoals of brands already consolidated in the market, and the city has no industrial processing of charcoal a possible investment to generate a good coal it is necessary to improve the standard of the product and become commercially competitive, manufacturing can improve by investing in improvements in technology and manufacturing process.
