Device and system for pyrolysis of waste

A pyrolysis system for waste, comprising:

• a pyrolysis apparatus configured to receive waste and generate combustible gas by pyrolyzing the received waste;
• an emulsification apparatus connected to the pyrolysis apparatus and configured to produce pyrolysis oil by cooling condensable gas among the combustible gas generated by the pyrolysis apparatus and discharge non-condensable gas;
• and
• a combustion furnace connected to the emulsification apparatus and configured to receive and combust the non-condensable gas discharged from the emulsification apparatus,
• wherein the combustion furnace is configured to generate hot air by combusting the non-condensable gas, and supply the hot air to the pyrolysis apparatus to pyrolyze the waste.

A method performed by a pyrolysis system that comprises:

• a pyrolysis apparatus, an emulsification apparatus connected to the pyrolysis apparatus, a combustion furnace connected to the emulsification apparatus, a main boiler connected to the pyrolysis apparatus, and an auxiliary boiler connected to the combustion furnace and the pyrolysis apparatus, the method comprising:
• generating, by the pyrolysis apparatus, a combustible gas by pyrolyzing waste;
• producing, by the emulsification apparatus, pyrolysis oil by cooling a condensable gas among the combustible gas received from the pyrolysis apparatus;
• combusting, by the combustion furnace, produced non-condensable gas discharged by the emulsification apparatus;
• supplying, by the combustion furnace, hot air generated by combusting the non-condensable gas to the pyrolysis apparatus;
• and
• generating, by the main boiler, steam based on hot air received from the pyrolysis apparatus, wherein
• the generating, by the pyrolysis apparatus, a combustible gas comprises:
• receiving waste;
• receiving the hot air supplied by the combustion furnace, and
• pyrolyzing the waste with the hot air supplied by the combustion furnace.
