1. 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.
