<p><P>PROBLEM TO BE SOLVED: To achieve switching and combined use of external heat and inner heat operation systems, with a simple device configuration. <P>SOLUTION: To a heating flow path 10 for external heating of an outer circumferential part of a kiln furnace 1, a hot wind generating furnace 11 is connected via a combustion gas supply line 13 with a flow regulating valve 16. A branched combustion gas supply line 14 with a flow regulating valve 17 branched from an upstream side position than the flow regulating valve 16 is connected to a combustion gas introduction part 15 on an inlet 2 side of the kiln furnace 1. In the external heat operation system, the flow regulating valve 16 is opened, and combustion gas 12 to be generated in the hot wind generating furnace 11 is flown to the heating flow path 10 to cause waste 6 in the kiln furnace 1 to be treated by pyrolysis gasification. In the inner heat operation system, the flow regulating valve 17 is opened, combustion gas 12 having oxygen concentration of more than 5% to be generated in the hot wind generating furnace 11 is introduced through a combustion gas introduction part 15 into the kiln furnace 1 to partially burn the waste 6, and with combustion heat thereof, pyrolysis gasification treatment of the waste 6 is performed. In the case of combined use, the flow regulating valves 16, 17 are opened together. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
