An incinerator for burning waste material includes a combustion chamber having spaced end walls and a side wall through which a mixture of waste material and air is introduced under pressure tangentially for establishing a vortical movement of the waste material toward one of the end walls. The waste material is ignited during its vortical movement and the chamber includes a discharge flue port near the one end wall which is concentric with the longitudinal axis of the chamber and which has an open end in the chamber spaced axially of the one end wall. A second discharge port adjacent the one end wall extends tangentially through the side wall for discharging from the chamber residual combustible material and non-combustible material entrained in the outer region of the vortex. The discharged material is conveyed through a conduit to a separator which separates the discharged gases and solid material. The separated gases and any solid particles suspended therein are introduced back into the chamber. A baffle is mounted on the flue adjacent its open end for deflecting outwardly toward the side wall solid material which moves from adjacent the one end wall toward the open end of the flue. The ratio of the area of the open end of the discharge flue port to the area of a cross-section of the chamber taken perpendicular to its longitudinal axis is selected to be within the range of one-sixteenth to four twenty-fifth and is preferably one-ninth. |
