Abstract

Abstract An incinerator for burning waste material includes a horizontally extending 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 extends tangentially through the chamber side wall adjacent the bottom of the chamber at one side thereof for discharging from the chamber noncombustible 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. 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. Means are provided for introducing secondary air into the chamber tangentially to the chamber side wall at a plurality of spaced regions which are aligned horizontally and which are located adjacent the bottom of the chamber at the other side thereof such that one of said regions is substantially opposite the second discharge port. Control means including dampers are provided for independently adjustably controlling the amount of secondary air flowing into the chamber at each spaced region. Also, automatic control means are provided for controlling generally the secondary air in accordance with variations of temperature within the chamber.
