Incinerator for burning waste and a method of utilizing same

An incinerator for burning waste comprising:

• a hollow body having an opened upper end forming an outlet and an opened lower end;
• a bottom plate closing the lower end, said bottom plate being cone-shaped;
• a central opening provided in the bottom plate for introducing pressurized oxidizing gas into the hollow body;
• a plurality of openings disposed in a circumferential direction of said bottom plate so that a pressurized oxidizing gas can make swirls along said cone-shaped bottom plate;
• an oxidizing gas feeding means for supplying gas to the central opening and the circumferentially disposed openings, said oxidizing gas feeding means comprising:
• a gas box surrounding said cone-shaped bottom plate into which pressurized gas is introduced;
• a pipe coupled to said central opening;
• and
• a smaller pipe provided within the other pipe and forming an annular clearance between the exterior of said smaller pipe and the interior of said other pipe whereby combustion residue is discharged through said annular clearance;
• and
• heat transfer medium particles provided in the hollow body and fluidized by the oxidizing gas introduced into the hollow body;
• and
• a means for feeding waste into the hollow body.
