Abstract: Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow.

Abstract: A vortex particle separator has an impeller at a housing inlet with impeller blades spiraling around an impeller shaft and longitudinal axis of the separator to impart either clockwise or counterclockwise rotation to air flowing through the impeller when viewed looking downstream along the axis. The upstream end of each impeller blade is inclined in a direction opposite to the direction the air rotates when passing through the impeller, measured from a radial baseline through the axis and the juncture of the blade with the center shaft of the impeller. Thus, in each orthogonal plane along the axial length of the impeller the juncture of the blade with the housing is offset from the baseline in the rotational direction opposite the direction in which air flows through the impeller. An offset angle of 45° to 55° is believed suitable.
