Uso de diferentes biomassas em olarias de três municípios da região central do RS: seu impacto energético na qualidade do produto e aspectos ambientais

Abstract

The aim of this study was to survey biomass residues which are used as fuel in brick kilns in three cities of central region of Rio Grande do Sul, through a socio-economic survey to ascertain the potential for power generation, as well as its economic viability .The object of study types s biomass (rice husk, wood chips, sawdust and wood), used as a source of fuel in furnaces of 12 potteries. In May 2010, April and August 2011, were collected ash brick kilns in 5 of the 12 surveyed, and analyzed in laboratories values of macro and micro nutrients, and carbon. Other data collected were the average consumption of biomass and average values to produce bricks. One can say that a matrix composed exclusively biomass energy is an interesting alternative analyzed in this study under the conditions of economically and environmentally, we conclude that they are viable use of waste ash as an alternative to continuous improvement of management environment by generating industries to rationalize the use of energy inputs and reduce the level of emissions. The amendment process is intended to generate savings in the purchase of energy inputs purchased in the market and contribute to the expansion of the power generation industry.
