Patent number: 9090844Abstract: A method for producing moldings, in particular briquettes, from fine-grained to medium-grained mixed material using organic binders. In a first stage, the mixed material is heated to a temperature necessary for the molding operation. In a second, atmospherically separate stage, mixing of the mixed material with binder is performed, as well as downstream steps of the process. The method allows hazardous emissions to be avoided.Type: GrantFiled: April 28, 2008Date of Patent: July 28, 2015Assignee: SIEMENS VAI METALS TECHNOLOGIES GMBHInventors: Wilhelm Fingerhut, Hado Heckmann, Leopold Werner Kepplinger, Kurt Wieder, Johann Wurm

Patent number: 8313552Abstract: A method and an apparatus for the production and the melting of liquid pig iron or of liquid steel intermediate products in a melt-down gasifier, with the introduction of oxygen-containing gas streams through oxygen nozzles into the solid bed. At least one oxygen nozzle has a single gas supply and introduces at least two gas streams. Using plural gas streams from a nozzle reduces the risk of fluidization of the solid bed because the number of gas raceways in materials in the gasifier is increased.Type: GrantFiled: November 4, 2008Date of Patent: November 20, 2012Assignees: Siemens Vai Metals Technologies GmbH, PoscoInventor: Leopold Werner Kepplinger

Publication number: 20100031668Abstract: A process for generating electrical energy in a gas and steam turbine (combined cycle) power generating plant with a gasification gas produced from carbon carriers and oxygen-containing gas. Carbon carriers are gasified in a gassing zone with oxygen or a gas containing a large amount of oxygen. Gasification gas produced is passed through a desulfurizing zone containing a desulfurizing agent. Used desulfurizing agent is fed into the gassing zone and drawn off after the formation of a liquid slag. Desulfurized gasification gas is burned in a combustion chamber. The resulting combustion gases H2O and CO2 are introduced into the gas turbine for energy generation. Downstream of the gas turbine, the combustion gases are separated in a steam boiler into water vapor and carbon dioxide. The water vapor is subsequently introduced into a steam turbine. The carbon dioxide is at least partially returned to the combustion chamber for setting the temperature.Type: ApplicationFiled: December 18, 2007Publication date: February 11, 2010Inventor: Leopold Werner Kepplinger

Patent number: 6569377Abstract: In a process for the direct reduction of particulate iron-oxide-containing material by fluidization, a synthesis gas is introduced as a reducing gas into several fluidized bed zones consecutively arranged in series. The reducing gas is conducted from one fluidized bed zone to another fluidized bed zone in counterflow to a flow of particulate iron-oxide containing material through the fluidized bed zones. In order to reduce operating costs and, in particular, the energy demand, various process parameters are varied according to the temperature of the iron-oxide-containing material in the first fluidized bed zone being adjusted to be below 400° C. (and, preferably, below 350° C.), above 580° C. (and preferably about 650° C.), or to a temperature within the range of from 400° C. to 580° C. If the temperature of the iron-oxide-containing material in the first fluidized bed zone is maintained to be below 400° C.Type: GrantFiled: January 15, 2002Date of Patent: May 27, 2003Assignee: Voest-Alpine Industrieanlagenbau GmbHInventors: Siegfried Zeller, Konstantin Milionis, Johann Reidetschläger, Leopold Werner Kepplinger, Johann Zirngast, Johannes Schenk, Roy Hubert Whipp, Jr.
