NOVELTY - Device for drying and torrefying biomass using waste heat of a power plant, comprises a drying device (24) for drying the biomass, a mixing chamber for a conditioning device, for mixing flue gas (10) from boiler (21) and/or turbine (22) of the power plant, the conditioning device for conditioning the dried biomass, a mixing chamber for a torrefaction device, for mixing the flue gas from the boiler, turbine and/or a combustion chamber (20) of the power plant, and the torrefaction device for torrefying the conditioned biomass to form a torrefied biomass.    USE - The device is useful for drying and torrefying biomass (claimed).    ADVANTAGE - The device requires less energy, and thus it is economic.    DETAILED DESCRIPTION - Device for drying and torrefying biomass using waste heat of a power plant, comprises a drying device (24) for drying the biomass to form a dried biomass, a mixing chamber for a conditioning device, for mixing flue gas (10) from boiler (21) and/or turbine (22) of the power plant to form a conditioning gas having a temperature of 200 degrees C, the conditioning device for conditioning the dried biomass to form a conditioned biomass, a mixing chamber for a torrefaction device, for mixing the flue gas from the boiler, turbine and/or a combustion chamber (20) of the power plant to form a torrefaction gas having a temperature of 300-400 degrees C, and the torrefaction device for torrefying the conditioned biomass to form a torrefied biomass. An INDEPENDENT CLAIM is also included for drying and torrefying the biomass using the waste heat from the power plant, comprising drying the biomass to obtain the dried biomass, mixing the flue gas in the mixing chamber to obtain the conditioning gas having a temperature of 200 degrees C, conditioning the dried biomass using the conditioning gas to obtain the conditioned biomass, mixing the flue gas in the mixing chamber to obtain the torrefaction gas having a temperature of 300-400 degrees C, and torrefying the conditioned biomass using the torrefaction gas to obtain the torrefied biomass.
