Torrefied Biomass Energy Efficiency

Torrefied biomass energy efficiency compares favorably with raw pellet production despite the high temperatures used in torrefaction. In the TorrB® process, all heat is provided by an average of 10% of the feedstock energy if the biomass contains less than 35% moisture.

In fact, despite the high temperatures used in torrefaction, the energy required to dry, torrefy and densify TorrB® briquettes is much less than that of producing standard wood pellets. Our TorrB® drying and torrefaction processes use a small portion of the feedstock for energy needs, while traditional pellets need an external energy source for drying.Grinding raw wood is energy intensive compared to grinding torrefied wood. And densifying into pellets is more energy intensive than our briquetting technology.

In comparison to other torrefaction technologies which use clean wood chips, HM3 Energy technology can use forest waste, a cheaper feedstock than clean wood chips or sawdust.
