Abstract: An incinerator for burning waste material includes a horizontally extended combustion chamber 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. A second discharge port extends for discharging from the chamber 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. 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. Additionally, control means are provided for the use of specialized sensors to monitor the temperature, air flow and volume of the chamber.
