PURPOSE: To prevent coking on the inner wall of a pipe and to realize a safe stable operation and an improvement in recovery of a produced oil by a process wherein waste material is thermally melted, continuously fed into a decomposition reactor, sent into a circulation pipe installed in a heating furnace and heated so that it is partly gasified and passed through the pipe at a specified flow rate, and then discharged into the decomposition reactor.
CONSTITUTION: Waste material, such as a waste oil or a low polymer, is thermally melted in a raw material melting unit 11; continuously fed into a decomposition reactor 1 by way of a raw material storage tank 14: sent through a pump 6 and a filter 7 into a circulation pipe 5 installed in a heating furnace 3 and heated preferably to 410-460°C so that it is partly gasified and passed through the pipe 5 at a flow rate of 3 m/sec or higher; and then discharged into the thermal decomposition reactor 1. The discharged gas is passed through a fractionating tower 2 and a condenser 22, and collected in a liquid receiver tank 23 for recovery as produced oil.
