Catalytic oxidizer

A catalytic oxidizer for reusing waste, which comprises:

• a cylindrical oxidation chamber, intended to be fed with catalytically oxidizable waste, and which comprises a chamber body and at least one wall that surrounds an outer part of the chamber body;
• a waste feeder which feeds the cylindrical oxidation chamber with oxidizable waste;
• a comburent supplier, which comprises nozzles connected to a lower part and a middle part of the cylindrical oxidation chamber and oriented in a tangential direction directing pressurized oxygenated gas in the oxidation chamber, and
• a recirculation system, which comprises:
• a particle separator in the upper part of the cylindrical oxidation chamber comprising a trap wherein hot particles of ash and unburned material are trapped, and
• a transporter comprising a lower pressure zone relative to the pressurized oxidation chamber whereby the lower pressure suctions the particles trapped in the particle separator, together with the combustion gases accompanying the hot particles of ash and the unburned material, from the separator to the base of the cylinder oxidation chamber.
