System and method for pyrolysis of plastics

A method of continuous pyrolysis, the method comprising:

• providing a pyrolysis system comprising:
• a pyrolysis chamber comprising a first input opening, and a first output opening;
• a heating chamber comprising a second input opening, and a second output opening;
• a feeding chamber comprising:
• a third feeding opening, opened to ambient atmosphere and arranged to receive grinded material;
• a third pressure opening;
• and
• a third output opening coupled to the first input opening of the pyrolysis chamber;
• a flame injector device coupled to the second input opening of the heating chamber and injecting ambient air and combustible material into the heating chamber;
• a pumping device comprising:
• an input opening coupled to the second output opening of the heating chamber;
• and
• an output opening coupled to the third pressure opening of the feeding chamber;
• a measuring apparatus comprising at least one of:
• a O2 sensor installed within the heating chamber;
• and
• a pressure transducer installed within the feeding chamber;
• and
• a controller electrically coupled to the measuring apparatus, to the pressure transducer, to the flame injector and to the pumping device;
• controlling, by said controller, the flame injector device, to inject at least one of said ambient air and said combustible material to maintain within the heating chamber O2 concentration between 8% and 10%, to effect pyrolysis in the pyrolysis chamber;
• and
• controlling, by said controller, the pumping device, to maintain pressure in the feeding chamber, above ambient pressure, to prevent ambient air from entering the feeding chamber via the third feeding opening.
