| Summary: | This paper compares briquettes made of spruce with those made of beech from the
perspective of physical, mechanical and energetic features, for the purpose of making the appropriate
selection from the market. The main properties being studied are briquettes' density, as a physical
feature, resistance to perpendicular compression, as a mechanical feature necessary to determine
chips' compression degree and their compression status, and the calorific value as an energetic
feature. The research findings show that coniferous tree briquettes are denser and more resistant, but
have a lower calorific value. It was also determined that briquettes compression is directly dependent
on their density and consequently, briquettes' energy density remains the only property able to
collectively characterise the quality of briquettes |
