Abstract: A method and an apparatus for decomposing halogenated hydrocarbon gas economically and stably without relying on any special treatment and without generating dioxins. A catalyst to decompose halogenated hydrocarbon gas, 4, is supported on a carrier 3. A target gas, which contains the halogenated hydrocarbon gas, is passed through the carrier 3, while heating the carrier 3 using an electromagnetic induction heating mechanism 5, 6.

Abstract: The object is to provide a method and an apparatus for decomposing halogenated hydrocarbon gas economically and stably without relying on any special treatment and without generating dioxins. The apparatus includes a carrier supporting a catalyst for decomposing halogenated hydrocarbon gas, wherein the carrier is resistant to a halogen-containing gas and is electrically conductive, the halogenated hydrocarbon gas passing through the catalyst which is supported by the carrier; and a heating mechanism for heating the carrier by an electromagnetic induction heating.

Abstract: A method for treating combustible wastes comprises the steps of: carbonizing combustible wastes to produce carbonized products and a combustible gas; contacting an exhaust gas from a process with said carbonized products to purify the exhaust gas; and recovering the carbonized products in the exhaust gas. The carbonizing is carried out at a temperature of 400° C. or higher.

Abstract: A method of blowing a synthetic resin material into a furnace comprising preparing a synthetic resin material having an average specific surface area of at least 50 m2/kg; and blowing the synthetic resin material from tuyeres of a shaft furnace for ironmaking.

Abstract: A method for disposing synthetic resinous material comprises: dechlorinating a synthetic resinous material by heating the synthetic resinous material and decomposing the same; and supplying the synthetic resinous material into the furnace as a fuel or a reducing agent. An apparatus comprises: a chlorine removing means for dechlorinating the synthetic resinous material by heating the synthetic resinous material; and a pulverizer for pulverizing the dechlorinated synthetic resinous material, a supply means for supplying the processed synthetic resinous material into a furnace.

Abstract: Disclosed herein is a scrap melting process for the production of molten iron from scrap (as the source of iron) and of high-calorie exhaust gas (as a valuable fuel gas) from pulverized coal (as the principal source of heat and a partial source of high-calorie exhaust gas) and waste plastics (as the principal source of high-calorie exhaust gas and a partial source of heat). The process comprises charging a shaft furnace (equipped with a burner at the tuyere) with scrap (as the iron source) and coke and optional waste plastics from the furnace top and injecting pulverized coal (or pulverized coal plus waste plastics) and oxygen through the burner under specific conditions, so as to mix together pulverized coal (or pulverized coal plus waste plastics) and oxygen, thereby achieving rapid combustion of pulverized coal etc.

Abstract: A method for blowing a synthetic resin material into a furnace which comprises processing film-shaped synthetic resins into a first granular resin material; crushing non-film-shaped synthetic resins into a second granular resin material; pneumatically feeding the first granular resin material and the second granular resin material to a furnace; and blowing the first and second granular resin material into the furnace.

Abstract: Provided herein is a scrap melting method capable of both producing a molten iron by efficiently melting scrap and producing a large amount of high calorie exhaust gas having a high utility value as a fuel gas and at the same time capable of performing such operation at a low production cost.

Abstract: A method for controlling a flow rate of gas for prereducing ore comprises the steps of prereducing ore in a prereduction furnace having a fluidized bed with a gas generated in a smelting reduction furnace and controlling a pressure of gas generated in the smelting reduction furnace and introduced into the prereduction furnace, thereby controlling the actual flow rate of gas introduced into the prereduction furnace. An apparatus for controlling a flow rate of gas for prereducing ore comprises a flow passage for introducing gas generated in a smelting reduction furnace into a prereduction furnace and a gas pressure control valve positioned in the flow passage.

Abstract: A prereduction furnace of a smelting reduction facility comprises a fluidizing prereduction chamber in the upper part of the prereduction furnace wherein iron ores are fed and prereduced, a gas blowing chamber installed in the lower part of the prereduction furnace wherein a reducing gas is fed, a distributor for separating the fluidizing prereduction chamber from the gas blowing chamber, and a discharge pipe for discharging the prereduced ore from the fluidizing prereduction chamber. The distributor includes a body of refractory material, a metal plate installed on the bottom of the body, nozzles passing through the body and the metal plate, metallic pipes inserted in the nozzles, and cooling pipes connected to the metal plate. A metallic box may be installed below the metal plate for providing passages for gas flow. A bottom plate may be installed spacedly below the metal plate, with nozzles passing therethrough. The distributor may comprise a rigid thick plate and a refractory layer thereon.
