Publication number: 20160265443Abstract: A gas turbine having a compressor is controlled at least by controlling an opening of variable inlet guide vanes between a maximum opening and a minimum opening. A function indicative of the mechanical stress undergone by compressor blades downstream of the variable inlet guide vanes has an increasing line trend from the maximum opening to the minimum opening of the variable inlet guide vanes. The function has operating windows in which the function is smaller than a stress limit and at least one intermediate window between two operating windows, in the intermediate window the function being greater than the stress limit. The variable inlet guide vanes are regulated with a given velocity when moving from one operating window to another operating window passing through an intermediate window.Type: ApplicationFiled: March 9, 2016Publication date: September 15, 2016Applicant: ANSALDO ENERGIA IP UK LIMITEDInventors: Sebastiano SORATO, Marco MICHELI, Wolfgang KAPPIS, Fulvio MAGNI

Patent number: 8943825Abstract: A Helmholtz damper for a combustor of a gas turbine includes first and second damping volumes. The combustor has a combustion chamber disposed in a housing and closed off by a front plate at which a plurality of burners are exchangeably fastened. The burners are supplied with fuel via fuel lances which extend from outside the housing through a bushing of the housing to the associated burner. The first damping volume has a first end and a second end, the first end of the first damping volume being configured to attach a connecting passage extending to a front panel such that the Helmholtz damper is connectable with the front plate of the combustion chamber in place of one of the burners. The second damping volume has a first end and a second end and is arranged in series with the first damping volume along an axis of the Helmholtz damper with the first end of the second damping volume being detachably connected to the second end of the first damping volume so as to form a combined larger damping volume.Type: GrantFiled: January 28, 2011Date of Patent: February 3, 2015Assignee: Alstom Technology Ltd.Inventors: Fulvio Magni, Martin Andrea Von Planta, Frank Grimm, Dariusz Nowak, Mischa Schaerer

Patent number: 8567198Abstract: An injection nozzle (10), especially for injecting liquid fuel, preferably crude oil, into the combustion chamber of a gas turbine, includes an inner chamber (16) which extends along a nozzle axis (19), conically tapers to a concentric nozzle orifice (17), and to which the medium which is to be injected is fed from outside through a plurality of inlet ports (18) which are arranged in a distributed manner around the nozzle axis (19). The inlet ports (18) are oriented perpendicularly to the nozzle axis (19) and each lead tangentially into the inner chamber (16). With such an injection nozzle, an improved spray cone is achieved by the fact that a pin (14), which extends in the axial direction, is concentrically arranged in the inner chamber (16) and passes through the region of the mouths of the inlet ports (18) and extends right into the nozzle orifice (17).Type: GrantFiled: February 12, 2010Date of Patent: October 29, 2013Assignee: ALSTOM Technology Ltd.Inventors: Fulvio Magni, Dariusz Nowak, Tomasz Dobski, Rafal Slefarski
