摘要： PROBLEM TO BE SOLVED: To improve a heat efficiency by suppressing useless heat dissipation toward outside in a combustion device where the fluidized-bed-type dry distillation oven of a solid fuel and the combustion oven of char being generated by dry distillation in parallel and communicating with each other. SOLUTION: A combustion device is constituted by arranging a dry distillation oven 1 for performing the dry distillation of a solid fuel A by a high- temperature bubbling flow layer and a char combustion oven for burning the char content of a dry distillation residue in parallel and performing connection by seal pots 6 and 6' where the splash particles of a fluid material bubbling are deposited and fluid material circulation ports 7 and 7' at one edge and the other edge of each oven. The closed loop of a fluid material 3 is formed through the dry distillation oven 1 and the char combustion oven, thus preventing heat being accumulated at the fluid material 3 from being dissipated outside, reducing heat loss, and improving heat efficiency.

摘要： PROBLEM TO BE SOLVED: To improve the dust collection efficiency of an electrostatic precipitator wherein an endless dust collecting electrode is additionally arranged. SOLUTION: In the electrostatic precipitator, a dust-containing gas is passed between a first discharge electrode 4 and a first dust collecting electrode 5 opposed to each other, the dust contained in the gas is charged by a corona discharge between the electrodes, and the charged dust is collected on the first dust collecting electrode 5 by the electrostatic force acting between the electrodes. The electrostatic precipitator is provided with a second discharge electrode 7-1 crossing the gas flow and arranged on the downstream side of the electrodes 4 and 5, a second dust collecting electrode 8 positioned on the downstream side of the second discharge electrode 7-1 and having an endless metallic net 13 circulating across the gas flow and a third discharge electrode 7-2 crossing the gas flow and arranged on the downstream side of the second dust collecting electrode 8.

摘要： PROBLEM TO BE SOLVED: 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. SOLUTION: 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.
