1. A system for continuous pyrolysis 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 flame injector and to the pumping device, and configured to maintain at least one of:
control 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%; and
control 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.
