How is DOING pyrolysis plant working?

Doing pyrolysis plants pyrolysis raw material (waste tire/tyres,waste plastic,rubber etc.) as follows:
Firstly, put the raw material into furnace
Secondly, burn the fuel material(coal, or wood, or natural gas, or oil ) in the combustion system. After finishing oil producing, the temperature of reactor will come down, at the same time, carbon black will be discharged automatically.
Lastly, when the temperature falls to 100 degree celsius, worker could open the door of  the reactor to discharge the steel wire, then can start another batch.
