Abstract

A furnace for effecting pyrolysis of waste material includes an essentially cylindrical cavity for effecting pyrolysis of the waste material rotating around its lengthwise axis, a combustion chamber located around the cavity and injectors for introducing fuel and comburant or oxidizing agent into said chamber. The injectors for introducing fuel and comburant are oriented tangentially to a wall of the combustion chamber so that flame or flames created by combustion of the fuel developed in the swirling fashion around the cavity containing the waste material. Also, the injectors are arranged to effect staged combustion within the combustion chamber.
