MAPPING THE FREQUENCY OF USE AND CHARACTERISTICS OF FOREST BIOMASS USED FOR POWER GENERATION LAGES, SANTA CATARINA STATE

Abstract

http://dx.doi.org/10.5902/198050987560The region of Lages, in Santa Catarina state, is the economy based on the forest industry, especially for primary processing, and this is characterized by low yields and high production of waste, constituting environmental problems, logistical and financial support. The use of biomass in co-generation systems has been an economically profitable, since the year 2005, the place of study. In this context, the aims of this study were to map the frequency of use and the availability of wood waste used for co-generating of energy in Lages, Santa Catarina, and to evaluate the energetic properties. The sample data and the results of the energetic properties of biomass samples used in a co-generating energy in the period 2005 to 2008. The residues were characterized in terms of moisture content, ash content, gross calorific value and net calorific value. The results showed that the most available residue is the pine bark, although the most energetically efficient ones were the chip with pine-bark and the mixture of all waste systems used in generating power.
