Analyses of Pellets Produced from Spruce Sawdust, Spruce Bark, and Pine Cones in Different Proportions

A lot of residual biomass has energy value and can be used for further applications through suitable treatments, such as pelletization. This treatment improve properties, mainly density, but also lead to problems due their low ash melting temperatures, high content, the formation harmful compounds during combustion. article deals with potential pellets produced from spruce sawdust, bark, pine cones in different proportions. The impact cone bark contents on pellet properties was observed. were measured, carbon, hydrogen, nitrogen, moisture, volatile, fixed ash, well calorific values temperatures. Based results, it concluded that addition sawdust affected nitrogen Despite this, all met standard EN ISO 17225-2 content lower at least B quality. However, only three samples five this A2 quality behavior. Therefore, they present an alternative fuel interesting potential.
