Abstract:
1. A cyclonic combustor comprising: a combustion liner forming a combustion chamber having a generally cylindrical shape and operable to have an ignition zone, a combustion zone, and a dilution zone arranged longitudinally along the axis of the combustion chamber; a biomass feed inlet at one end of the combustion chamber formed through the combustion liner for receiving biomass particles under pressure, wherein the biomass feed inlet is formed so that the biomass particles are introduced into the ignition zone of the combustion chamber with a tangential component relative to the longitudinal axis of the combustion liner; a plurality of air tuyeres formed through the combustion liner for receiving compressed air, an outer casing having a generally cylindrical shape and surrounding the combustion liner; an inner lining having a generally cylindrical shape and surrounding the combustion liner so as to define at least two air plenums between the outer casing and the combustion liner wherein the at least two air plenums are in communication with the combustion chamber via the plurality of air tuyeres so that the compressed air is supplied to the combustion chamber through the at least two air plenums; and
