Patent number: 9976564Abstract: A radial compressor unit for compressing gas has several compressor stages. Each compressor stage includes an impeller having rotor blades, and a flow channel arranged downstream of the impeller, as viewed in the flow direction of the gas to be compressed, having a diffusor section, a deflection section, and a recirculation section having guide blades. The gas compressed in a compressor stage can be removed as cooling gas for cooling a component to be cooled, and can be conveyed in the direction of the component to be cooled. The cooling gas can be removed adjacent to an intermediate wall of the compressor stage from the deflection section and/or the recirculation section of the flow channel of the compressor stage.Type: GrantFiled: February 27, 2013Date of Patent: May 22, 2018Assignee: MAN Diesel & Turbo SEInventors: Dirk Bueche, George Kleynhans, Bob Mischo

Patent number: 7198483Abstract: Arranged upstream of each swirl-stabilized premix burner (1) of a burner system there is respectively an adjustable distributing device (5) with control valves (V1, . . . , V8) and/or on/off valves (V?1, . . . , V?16), by means of which various axial mass flow distributions of the fuel introduced can be set. Preferably, those which have particularly favorable values with respect to characteristics such as NOx emission and maximum amplitudes of pulsations occurring are chosen. For this purpose, Pareto solutions are determined with respect to the said characteristics, in that a distributing device (5) is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device (5) is set by means of a control unit are iteratively generated in a data-processing system by an evolutionary algorithm.Type: GrantFiled: January 30, 2002Date of Patent: April 3, 2007Assignee: Alstom Technology Ltd.Inventors: Dirk Bueche, Rolf Dornberger, Petros Koumoutsakos, Christian Oliver Paschereit, Bruno Schuermans, Peter Stoll

Patent number: 7137809Abstract: In the case of swirl-stabilized premix burners (1), an axial mass flow distribution of the fuel introduced which has especially favorable values with respect to characteristics such as NOx emission and maximum amplitudes of pulsations occurring is used. For this purpose, Pareto solutions are determined with respect to the said characteristics, in that a distributing device (5) with control valves is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device (5) is set by means of a control unit (10) are iteratively generated in a data-processing system (9) by an evolutionary algorithm. On the basis of the values determined by a measuring unit (11), solutions which are especially favorable with respect to the characteristics mentioned, espectially Pareto-optimal, are selected. The distributing devices or the premix burners of the burner system are then formed in a way corresponding to such a solution.Type: GrantFiled: January 30, 2002Date of Patent: November 21, 2006Assignee: Alstom Technology Ltd.Inventors: Dirk Bueche, Rolf Dornberger, Petros Koumoutsakos, Christian Oliver Paschereit, Bruno Schuermans, Peter Stoll
