Abstract
A torrefaction method comprises forwarding biomass through a process chamber; heating the biomass in the process chamber to a predetermined temperature and pyrolyzing the biomass to release syngas from the biomass, wherein the syngas contains at least 20% of the power contained in the flow of the biomass; and oxidizing the syngas to heat the biomass in the process chamber.
Claims20
A torrefaction apparatus comprising:
- a process chamber arranged to accommodate a torrefaction process of biomass;
- an oxidizer arranged to heat the process chamber;
- and
- a conduit for syngas emitted from the biomass during the torrefaction process;
- wherein the conduit is arranged to guide the syngas from the process chamber to the oxidizer;
- and wherein the oxidizer is configured to provide an oxidation of the syngas releasing a power of at least 20% of the power contained in a maximum flow of biomass through the process chamber.
