Abstract
A process and apparatus for thermal treatment and stabilization of waste materials in which waste material is introduced into an uppermost first combustion zone of a vertically oriented combustion chamber and a fuel and an oxidant are tangentially injected into the first combustion zone, oxidizing at least a portion of any organic material in the waste materials and melting at least a portion of any inorganic material in the waste materials. A second portion of fuel and oxidant is injected into a second combustion zone disposed immediately below and in communication with the first combustion zone, melting any remaining inorganic material in the waste material after which the melted waste material is removed from the bottom area of the combustion chamber for disposal.
