To improve combustion efficiency by enabling high temperature combustion by preventing the flowing in of a chlorine component into a combustion melting furnace in a waste burning system.
Dry distillation gas 20 generated by distilling waste 10 in a distillation furnace 101 is dropped with temperature at a heat exchanger 105 and demineralized by a first wet type demineralizer 102 after collected and separated with fluid residue 30 by a separator 108. Demineralized dry distillation gas 20a is fed into a combustion melting furnace 103 after pressurized by a blower 106 and heated by a heat exchanger. The illiquid residue 40 remaining inside the dry distillation furnace is demineralized by a second wet type demineralizer 109. The demineralized dry distillation gas sent to the combustion melting furnace is burnt together with the fluid residue and the illiquid residue from the separator and the second demineralizer, and the combustion gas 60 of it is sent to a boiler 104. Water 50 used by the second demineralizer is used by the first demineralizer again and then drained after neutralized by a neutralizing device 110.
