Abstract: A rotary incinerator for disposal of industrial waste is provided. The incinerator is slopedly and rotatably disposed to a slant support and has a plurality of spirally arranged tubular conveying ribs on entire inner periphery for squeezedly transmitting the incinerating waste from the lower portion to an exit in the tapered upper end so that the waste is stirred while incinerating and the slag and ash are automatically discharged via the exit, a combustion system worked together with a ventilation system at a lower end for supplying the flame and the fresh air into the incinerator, a drive system for driving the incinerator to rotate and a control device for controlling the operation of the above recited elements. The improvement is characterized in safe and rapid incineration of the industrial waste, therefore, economical.
