A direct-fired biomass-fuelled pressurized gas turbine system comprising: a pressurized biomass particles feed system with a plurality of chambers and valves, and an air compressor; a cyclonic combustor for combustion of biomass particles under pressure, comprising: - a combustion liner (420) forming a combustion chamber of generally cylindrical shape, a biomass feed inlet (414) to introduce biomass particles into the combustion chamber with a tangential component relative to the longitudinal axis of the combustion liner (420), and a plurality of tangential air tuyeres (430a, 430b, etc.); - an intermediate lining (910) having a generally cylindrical shape and surrounding the combustion liner (420); - an outer casing (410) of generally cylindrical shape and surrounding the intermediate lining (910); - several air plenums (810, 820, 830) defined between the intermediate lining (910) and the combustion liner (420), and being in communication with the combustion chamber (420) via the plurality of air tuyeres (430a, 430b, etc.); - a cooling plenum (920) defined between the outer casing (410) and the intermediate lining (910), and in communication with the air plenums (810, 820, 830) through the intermediate lining (910). |
