ABSTRACT
Combustion and co-firing of biomass with coal in natural form has become a major
hurdle, primarily due to low energy density, structural heterogeneity and wide moisture
variations. Thermal pretreatment or torrefaction of biomass under anoxic condition can address
the above issues and transform into an energy dense and consistent quality solid biomass fuel.
This paper investigated the torrefaction of pine wood chips and logging residues at
temperatures ranging from 225oC to 300oC and 30 min residence time using a laboratory scale
batch torrefaction reactor. Change in mass loss, chemical compositions, moisture content and
heating value of biomass after each torrefaction condition was determined. Grinding
performance of torrefied biomass was evaluated by determining energy required for grinding;
particle size distribution and average particle size produced and were compared with raw
biomass and coal. Specific energy consumption for grinding of torrefied biomass decreased
significantly with increase in torrefaction temperatures. It was reduced to as low as 24 kWh t-1
at 300oC torrefaction temperature due to brittle nature of torrefied biomass. The energy density
of torrefied biomass increased with increase in torrefaction temperature. Torrefaction of
biomass clearly showed the improved fuel characteristics and grindability of biomass closer to
coal.
Keywords: Torrefaction, wood chips, logging residues, grinding energy consumption, fuel
characteristics, coal.
