Abstract:
Caragana korshinskii Kom is an important feedstock for producing high-quality solid fuel which possess excellent physical characteristic. In this study, the bonding mechanisms and failure mechanisms at microscopic perspective were analyzed combining the physical characteristics of briquettes. The Scanning electron microscope (SEM) images showed that bonding between particles was created through short-range forces and solid bridge. The short-range forces in fine particles could increase the density of briquette but could not resist the disruptive forces. The solid bridges were made mainly by natural binders such as lignin and mechanical interlocking in the fibers, flat shaped particles and bulky particles. The appropriate moisture and temperature in the range of glass transition is essential to produce high quality briquettes. The interface failure of solid bridge caused the destruction of bulky particles; the cohesive failure caused the destruction of the fine particles
