Cyclonic thermal treatment and stabilization of industrial wastes

In a vertically oriented combustor for treatment and stabilization of waste material having at least one combustor wall forming a plurality of axially aligned combustion zones, the improvement comprising:

• primary means for tangentially injecting a first portion of a fuel and an oxidant into an uppermost first combustion zone of said combustor;
• means for introducing said waste material into said first combustion zone;
• secondary means for injecting a second portion of said fuel and said oxidant into a second combustion zone disposed immediately below and in communication with said first combustion zone;
• means for removing treated waste material from said combustor in communication with said second combustion zone;
• and
• means for exhausting products of combustion from said combustor in communication with and disposed downstream of said second combustion zone.
