Resumo
The search for renewable energy source is growing on a large scale over the past few years. In all industry segments, the market competitiveness encourages investments in new researches to improve the efficiency of energy obtaining processes. Within this scenario arises an alternative source of renewable energy, the use of torrefacted biomass as solid fuel in cofiring with coal or charcoal, currently employed on large scale. This paper aims to study a method for mapping and definition of operational parameters of an innovative electrical vibrating thermal system, in order to provide the residence time to continuous process. Due to system versatility it is necessary to make a study of the combination parameters: motor angle, counter weight balance and frequency, in order to achieve the desired residence time. By the use of homogeneous sets of biomass samples, was possible to map the range of residence time available to complete a circulation cycle of biomass in the system (0:54 - 2:42 min). It can be concluded according to the methodology adopted was possible to determine the range of residence times and their settings for this new reactor concept.
