Patent number: 9862900Abstract: The invention relates to an oxygen lance that has at least three mutually coaxial pipes, each of which delimits at least one annular gap. The outermost pipe is designed to conduct superheated steam and has a steam supply point, the central pipe is designed as an annular gap, and the innermost pipe is designed to conduct oxygen at a temperature of no higher than 180° C. and has an oxygen supply point. A temperature sensor is arranged within the innermost pipe, said temperature sensor extending to just in front of the opening of the innermost pipe. The innermost pipe tapers in the form of a nozzle before opening; the innermost pipe opens into the central pipe; and the opening of the central pipe protrudes farther relative to the opening of the outermost pipe.Type: GrantFiled: August 8, 2013Date of Patent: January 9, 2018Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Ralf Abraham, Domenico Pavone, Reinald Schulze Eckel, Dobrin Toporov, Simon Boris Hafner

Publication number: 20150322356Abstract: A method for heating a high-temperature Winkler gasifier during the start-up of the gasifier includes the use of at least one burner for heating purposes. A gasifier head of the Winkler gasifier is assigned a cyclone with a return conduit for returning the particles separated off in the cyclone into the fluidized bed in the lower region of the gasifier, by means of which method the heating of a high-temperature Winkler gasifier is simplified and made substantially independent of the structural size of the gasifier. The at least one burner, which is installed in the head region of the gasifier and which acts downward into the interior of the gasifier, allows gas flow to be generated in the reverse direction through the return conduit of the cyclone.Type: ApplicationFiled: November 29, 2013Publication date: November 12, 2015Applicant: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Domenico Pavone, Dobrin Toporov, Ralf Abraham

Patent number: 8951316Abstract: A process for the production, treatment and combustion of synthesis gas for the purpose of generating electric power is disclosed. The synthesis gas is produced from a solid, carbon-containing fuel with the aid of an oxygen-containing gas and treated by a slag-separating device and a device separating alkalis. Subsequently, the synthesis gas produced is fed to an expansion turbine where the pressure energy is used for generating power. On account of the treatment and separation of alkalis the expansion turbine is protected from corrosion and mechanical impact. The expanded synthesis gas is then burnt under pressure and the combustion is used in a combined-cycle process using a gas turbine, steam generator and steam turbine for generating power. The process thus has an increased efficiency. Apparatus for use of the process is also described.Type: GrantFiled: May 15, 2009Date of Patent: February 10, 2015Assignee: ThyssenKrupp Industrial Solutions AGInventors: Ralf Abraham, Domenico Pavone

Patent number: 8877097Abstract: With a method for the generation of synthesis gas by means of gasification of solid or liquid carbonaceous fuels with an oxidation agent containing oxygen, in a reactor, wherein the synthesis gas is passed out of the reactor overhead, and the mineral ash/slag droplets that occur during the reaction are passed out of the reactor downward, in the direction of gravity, it is supposed to be made possible to use a flue-tube boiler, which is clearly less expensive, for heat removal in place of radiant boilers. This is achieved in that the synthesis gas is passed over a hot-gas filter (2), without being cooled, and subsequently passed through a flue-tube boiler (3), for cooling, wherein ash/slag particles precipitated on the hot-gas filter (2) are passed back into the gasification reactor (1), in the direction of gravity.Type: GrantFiled: September 2, 2011Date of Patent: November 4, 2014Assignee: ThyssenKrupp Uhde GmbHInventors: Johannes Dostal, Domenico Pavone

Patent number: 8512444Abstract: With a method and a system for treatment of a hot crude gas generated by an entrained flow gasification system, removal of the compounds that contain sulfur and carbon is supposed to be undertaken in such a manner that hot gas is made available for further use. This is achieved in that a desulfurization (7) follows the gasifier (2), in series, in the flow path of the hot gas, followed by a solid separation (8, 9), whereby behind the solid separation (8, 9), a partial stream (13) of the gas is provided downstream by way of a water quench (14), a Venturi scrubber (15), a crude gas cooler (16), as well as an H2O separation (17) and a compressor (18), the flow path (19) of which is passed back, cooled, into the circuit, behind the gasification (2) and ahead of the desulfurization system.Type: GrantFiled: September 9, 2009Date of Patent: August 20, 2013Assignee: ThyssenKrupp Uhde GmbHInventors: Ralf Abraham, Michael Rieger, Domenico Pavone, Olaf Von Morstein
