Abstract

This project aims to develop a production system for torrefied biomass briquettes by means of the inclusion of a continuous torrefier in traditional briquetage plants. The proposal is based on results obtained earlier, in which it was proved that torrefication is a procedure capable of improving the energy characteristics of biomass briquettes, preserving their main mechanical properties. A system of this type is capable of manufacturing highly standardized briquettes and with a high energy content, that’s to say, a better quality product for industrial, commercial and domestic use with export potential. The objective of this phase of the project is to research the technical viability of the proposed system, envisaging three fundamental steps for this. The first concerns the study of biomass residues (raw materials) and efficient technologies for the production of briquettes more suitable for the torrefication process. In the second stage, torrefied briquette samples will be produced to characterize them and study their performance during their combustion in industrial, commercial and domestic ovens. In the third stage the most appropriate variants for continuous torrefication will be studied. As a result, it is hoped to obtain the preliminary design of a continuous torrefier, including the principal control mechanisms for temperature, transport and cooling of the torrefied briquettes.
