摘要:
The invention relates to a facility for drying and roasting biomass comprising: - a drying reactor (U1) and a roasting reactor (U2), - a first burner (U4) and a second burner (U5), distinct from the first burner, - a heat recuperation element (E3), connected to the outlet of the first burner and designed to recuperate at least some of the heat available in the combustion gas emanating from the first burner and transfer it to the drying gas in order to heat the latter before it enters the drying reactor, - a first heat exchanger (E2), designed to recuperate at least some of the heat available in the gas emanating from the drying after it is has passed through the drying reactor and transfer it to the combustion air in order to preheat the same before it enters the first burner.
