<p>PROBLEM TO BE SOLVED: To reduce a running cost, eliminate troubles such as a high temperature corrosion caused by hydrogen chloride and provide an excellent control accuracy in a dry distillation and thermal decomposition melting combustor for a waste. SOLUTION: A dry distillation and thermal decomposition melting combustor for a waste comprises a dry distillation and thermal decomposition reactor 2 which carries out a dry distillation and a thermal decomposition on a waste C to produce a dry distillation gas G and a thermally decomposed residue D, a hot blast furnace 12 which supplies a combustion gas as a heating gas K into the dry distillation and thermal decomposition reactor 2, a melting combustor 4 which melts and burns the dry distilled gas G and fine particles I contained in the thermally decomposed residue D, a waste heat boiler 7 which recovers a combustion heat of the melting combustion 4, and a steam turbine generation set 14 which is driven with a steam S generated by the waste heat boiler 7. Between the dry distillation and thermal decomposition reactor 2 and the hot blast furnace 12, an electric heater 25 which uses an electric power fed from the steam turbine generation set 14 is disposed. The low temperature heating gas K generated by the dry distillation and thermal decomposition reactor 2 is supplied to the electric heater 25 and is heated there by an electricity and the heating gas K is supplied to the dry distillation and the thermal decomposition reactor 2.</p> |
