| 161 | Manipulation of the exit gas flow in a melting furnace | US643928 | 1991-01-22 | US5173919A | 1992-12-22 | Erwin Schmidl; Markus Hubig; Michael Hirth; Christian Wieckert |
| In a melting furnace (1), toxic, volatile chemical compounds from introduced filter dust from industrial incineration units are vaporized at about 1300.degree. C. and forced to leave the reaction space. The non-vaporizing residue forms a glassy melt which is discharged continuously or intermittently from the reaction space. Heating of the melt and of the filter dust is affected by resistance heaters in protective ceramic sheaths (4) above the melt (2). In order to prevent corrosion of the resistance heater protection sheaths (4) by exit gases (7) especially in the flow lee thereof, the exit gases are forced, by partitions (10) and an exit gas extraction pipe (9) with an inlet orifice (16) at a low level, to flow below the resistance heater protection sheaths (4) to an exit gas outlet (5). The partitions (10) reach with their underside (14) from a ceiling region (17) into the gas space of the melting furnace (1) preferably to a level lower than that of the underside (15) of the resistance heater protection sheaths (4). | ||||||
| 162 | Method for preventing dust depositions or build-ups in off-gas channels of electrothermal smelting furnaces | US710147 | 1985-03-11 | US4649807A | 1987-03-17 | Torbjorn Aasen; Bjarne Thogersen |
| A method for preventing deposits or build-ups of dust in off-gas channels for dust-containing off-gases from electrothermal smelting furnaces. This is done by blowing an additional gas tangentially into the furnace off-gas channels at the positions where build-ups or deposits of dust normally occurs. Hence a gas spiral is provided between the inner wall of the furnace off-gas channels and the dust-containing, hot furnace off-gas. Recirculated and cooled furnace off-gas is preferably used as additional gas. For open furnaces where the furnace off-gas is completely combusted before it enters into the furnace off-gas channels, air can be used as additional gas. The temperature of the additional gas is preferably kept below the sintering temperature of the dust in the furnace off-gas. | ||||||
| 163 | Rotary high temperature reactor | US551924 | 1983-11-15 | US4541346A | 1985-09-17 | Michael D. Culliford |
| A rotary drum 2 is provided with vanes 26 extending longitudinally thereof defining passages 21 therebetween with gas to be fed to the reactor being fed only to those of the passages 21 the outlets from which into the reactor are covered by the solid material 20 being tumbled therein. Within this arrangement it can be ensured that the hot gases being used to treat the solid materials can be passed through the solid material as it is being tumbled in the reactor with the reactor being capable of accepting a large range of different materials with a variation of particle and lump size. The reactor in its preferred exemplary form is used for starved air incineration of waste materials, the gas supply means being used to supply gas in an amount insufficient to complete the reaction in the drum such that combustible gases leave the outlet end for use in the burner 10 used to provide the hot gases to the reactor drum. | ||||||

A supply of high temperature water is provided for multi-stage cleaning and rinsing in the manufacturing operation.The combined exhaust from all of the ovens at 25% LEL is preheated in a heat exchanger and then all of the combustible components are burnt off by passing through the flames of an incinerator grid burner. The effluent from the burner first passes through the heat exchanger to preheat said oven exhaust gases and then through hot water coils to provide all of the necessary hot water for the system. High pressure hot water (275.degree.) is provided in this heat exchange operation. The hot gasses from the last heat exchanger, completely free of combustible contaminates, are mixed with fresh air to supply hot air for the dryers used in the process. There is a substantially complete recovery of heat and the gasses discharged to atmosphere meet air quality standards. | ||||||

| A method and apparatus for extracting bitumen and other hydrocarbons from oil-wetted tar sands and converting it to useful petroleum products, the method comprising first mixing the tar sands material with a condensate consisting oil material and agitating the resulting slurry. After agitating the slurry it is passed through a dual-phase centrifuge and the bitumen and heavy end hydrocarbons are removed, while the light end hydrocarbons remain in the centrifuge cake. The centrifuge cake is heated as it passes through an indirect fired rotary thermal desorber and the hydrocarbon material evaporates are cooled in a quench tank to be collected in the quench supply and recovery tank. The process can also be applied to materials which have become contaminated by hydrocarbons, to extract and remove the hydrocarbons. Another embodiment of the process involves using the indirect fired rotary thermal desorber to treat either tar sands material or a centrifuge cake and quenching the hydrocarbon material evaporates within the quench tank to be collected in the quench supply and recovery tank. | ||||||

| A method reduces carbon dioxide resulting from a steel production process. The carbon dioxide is reacted with an electropositive metal in combustion to produce carbon monoxide. The resultant carbon monoxide is fed back into the steel production process. In this method, the carbon monoxide can be used in a direct reduction method as a reduction gas or can be fed to a blast furnace process. The reacted metal can also be recovered by electrochemical conversion from its oxides or salts. In particular, a form of regenerative energy can be used to recycle the electropositive metal. | ||||||
