BIOMASS ENERGY GENERATION

A flue gas treatment system 20 for a pyrolysis-based biomass energy generation system, the flue gas treatment system comprises a circulation of solvent for absorbing carbon dioxide from the flue gas, a heat exchanger 22 located along the flow path of the solvent, for heating the solvent and a heat transfer fluid arranged to circulate between the heat exchanger and the biomass energy generation system 10. The heat transfer fluid absorbs heat from a heated fluid of the biomass energy generation system and transfers the heat to the circulation of solvent via the heat exchanger. Also disclosed are further inventions relating to a feedstock drier for a biomass energy generation system, and a biomass energy generation system. The flue gas treatment system makes use of heat from the energy generation system that otherwise might be wasted, thereby increasing the efficient use of the generated energy, and increasing the amount of carbon dioxide removed per unit of energy output by the energy generation system.
