| 20130294473 | MELTING APPARATUS FOR MELT DECONTAMINATION OF RADIOACTIVE METAL WASTE - Disclosed herein is a melting apparatus for melt-decontaminating radioactive metal waste. The melting apparatus includes a melting furnace, a high frequency generator, a ladle, a bogie, a cooling unit and a dust collector. The melting furnace includes a crucible into which the metal waste is input, and an induction coil which is wound around the crucible to melt the metal waste. The induction coil has a hollow hole in which cooling fluid flows. The high frequency generator applies high-frequency current to the induction coil. The ladle supplies molten metal, from which slag has been removed in the crucible, into molds. The bogie is disposed adjacent to the ladle and is provided with the molds, each of which forms an ingot using the molten metal supplied thereinto. The cooling unit cools the cooling fluid and circulates it along the induction coil. The dust collector filters out dust and purifies gas. | 11-07-2013 |

| 20140198819 | METHOD OF RECOVERING ENERGY FROM AN ELECTRIC INDUCTION FURNACE EXHAUST GAS IN THE GASIFICATION OF FEED FUEL TO EXHAUST GAS - A method of recovering energy from an electric induction furnace exhaust gas in the gasification of feed fuel to exhaust gas. Melt of an electrically conductive material, which is disposed within electric induction furnace, is pressurized while substantially sealing the electric induction furnace to enable the build-up of a superatmospheric pressure in said furnace. A feed fuel is injected into contact with at least a portion of the melt of electrically conductive material. Exhaust gas generated at a superatmospheric pressure is withdrawn from said furnace and scrubbed and stored for subsequent use in a gas accumulator. The total calorific value of the exhaust gas from the gas accumulator that is available for use by a gas consumer device is measured and estimated. An input of feed fuel, of auxiliary gases and of heating power to the electric induction furnace is adjusted such that the estimated total calorific value of exhaust gas is kept between a pre-determined upper and a pre-determined lower threshold by using an adjustable controller unit that comprises a PD controller. A gas consumer device is fed with the exhaust gas from the accumulator independently of the blowing periods. The electric induction furnace exhaust gas is maintained under superatmospheric pressure during the blowing, withdrawing, scrubbing and storing steps without recompression. | 07-17-2014 |
| 20140247856 | SLAG-SUPPLYING CONTAINER FOR USE IN ELECTRIC FURNACE FOR REDUCTION PROCESSING OF STEEL-MAKING SLAG - This slag-supplying container of an electric furnace for reduction processing of steel-making slag includes: a container body that causes hot steel-making slag to flow to the electric furnace; a slag discharging portion connected with an electric-furnace-side slag-supplying port; a slag receiving portion that receives the hot steel-making slag supplied; a lid that opens and closes the slag receiving portion; an exhausting portion that discharges exhaust gas from the electric furnace; and, a tilting unit that tilts the container body to adjust the amount of inflow of the hot steel-making slag to the electric-furnace-side slag-supplying port. | 09-04-2014 |
| 20150139265 | TILTING FURNACE - A furnace for melting and/or gasifying material, comprising a housing for temporary enclosure of said material, a supply opening through said housing, heating means, a discharge opening through said housing, a gas outlet through said housing, wherein said housing is mounted tiltable around a horizontal axis, said supply opening extending coaxially with said horizontal axis, and the discharge opening being mounted in a wall of the housing so that said melted material can be removed from the housing by tilting the furnace about said axis. | 05-21-2015 |
