To solve problems in a conventional combustion (treatment) system of a flame-retardant high-viscosity waste such as PCB which is mainly treated by chemical decomposition treatment technology that the chemical treatment method needs a large amount of initial running costs, on the other hand, an incineration treatment method is difficult in removal of a harmful substance in an exhaust gas, in particular, tar, so that it is difficult to actually execute the method, and agreement of residents of a construction area and/or its environment can not be obtained.

This combustion system of flame-retardant high-viscosity waste such as PCB is composed of a crusher for crushing an electric device incorporating PCB, a viscosity adjustment separating device for separating the crushed electric device and PCB, lowering the viscosity of PCB and performing separating treatment under a negative pressure, a main combustion chamber connected through a temperature retaining pipe disposed in the viscosity adjustment separating device, a deposit burner connected through a pipe disposed in the viscosity adjustment separating device, and an exhaust gas temperature decreasing chamber receiving exhaust gases of the main combustion chamber and the deposit burner.
