| 20110013662 | PROCESS AND PLANT FOR THE THERMAL TREATMENT OF FINE-GRAINED SOLIDS - A process for at least one of a chemical and a physical treatment of fluidizable substances in a reactor. The process includes introducing a hot gas into an interior of the reactor through a gas supply tube and cooling at least one of the hot gas and the gas supply tube with a coolant. The cooling is performed by contacting the hot gas with the coolant so as to provide a temperature of a wall of the gas supply tube at least 50° C. lower than a temperature of the gas at an inlet of the gas supply tube facing away from the interior of the reactor. | 01-20-2011 |
| 20110286490 | Method of Producing Activated Carbon Material - A method for producing an activated carbon material, such as a tape or belt of carbon fibres, includes within a reaction chamber causing relative movement between a carbon-containing substrate and an electric arc in a gap between two electrodes or adjacent an electrode so that an electric arc exists between the electrode and the substrate to heat the substrate to a substrate surface temperature effective to activate the carbon-containing substrate and above about 3750K. The activated material has high adsorbency, and increased capacitance and conductivity. | 11-24-2011 |
| 20110292961 | METHOD AND DEVICE FOR CONTROLLING A CARBON MONOXIDE OUTPUT OF AN ELECTRIC ARC LIGHT OVEN - In a method and a device for controlling a carbon monoxide output of an electric arc oven, comprising an oven container, an arrangement for determining a height of a foamed slag in at least three zones of the oven container on the basis of a solid-borne sound measurement, at least one first device for controlling an oxygen infeed, and at least one second device for controlling a carbon infeed into the oven container, the height of the foamed slag is determined in each of the at least three zones and associated with a carbon monoxide content in the exhaust gas of the electric arc oven, wherein the carbon infeed and/or the oxygen infeed in at least one of the at least three zones is controlled such that the height of the foamed slag is maintained below a maximum value. | 12-01-2011 |
| 20120140787 | METHOD AND DEVICE FOR DETERMINING A TEMPERATURE T OF A METAL MELT WITHOUT CONTACT - A temperature T of a metal melt in a furnace is precisely determined without contact using at least one burner gun unit fed through a furnace wall of the furnace above the metal melt into a furnace chamber and at least one temperature measuring unit downstream of the burner gun unit. | 06-07-2012 |
