20090025395 | Swirler for Use in a Burner of a Gas Turbine Engine - Disclosed is a swirler for use in a burner of a gas turbine engine, the swirler comprising a plurality of vanes arranged in a circle, flow slots being defined between adjacent vanes in the circle, each flow slot having an inlet end and an outlet end, in use of the swirler a flow of fuel and air travelling along each flow slot from its inlet end to its outlet end such that the swirler provides a swirling mix of the fuel and air, at least one vane having an edge adjacent an inlet end of a flow slot configured to generate within the flow slot one or more flow vortices that extend along the slot thereby to enhance mixing of the fuel and air travelling along the slot. | 01-29-2009 |
20090170043 | Arrangement for Preparation of a Fuel for Combustion - The invention relates to an arrangement for preparation of a fuel for combustion including a burner, a combustion chamber associated with the burner and in which combustion of a fuel is to take place in use of the arrangement as well as means for supplying liquid fuel to the arrangement through an internal passage in the burner for said combustion, solid portions of the burner body being heated by said combustion in use of the arrangement, wherein said internal passage is located inside said solid portions of the burner body for receiving heat energy evaporating said fuel from these body portions, and that it comprises means for conveying vaporized fuel to the combustion chamber to take part in the combustion. | 07-02-2009 |
20090249793 | Apparatus for Modifying the Content of a Gaseous Fuel - There is described an apparatus for modifying the content of a gaseous fuel comprising: a supply of the gaseous fuel; a supply of an oxidant; and a combustion device for utilising the oxidant to partially combust a first proportion of the fuel thereby to produce products of the partial combustion including intermediate combustion products, the products of the partial combustion mixing with the remaining proportion of fuel not partially combusted thereby to provide the modified fuel, wherein the partial combustion is controlled so as to provide the intermediate combustion products required to produce a predetermined modified fuel. | 10-08-2009 |
20090287448 | In on or Relating to Rotating Machines - A rotating machine, has a rotary component, which includes a memory device for storing data relating to the past use of the component. The data are associated with rotational speed and ambient temperature, which are detected by detectors either on or off the rotary component. The stored data may be the raw temperature and speed data as sampled over time, which are then used to derive values of low-cycle fatigue and creep damage. These fatigue and creep values are, in turn, correlated with the load profiles of the component to arrive at a value of elapsed lifespan for the component. Alternatively, the stored data may be the fatigue and creep values and/or, preferably, values of elapsed and remaining lifespan of the component. In a second embodiment the detectors are located on the machine casing along with an evaluation unit. | 11-19-2009 |
20100107649 | Gas Turbine Engine With Fuel Booster - A gas turbine engine including a compressor section, a combustor section including a combustor, a turbine section, a gaseous fuel supply conduit with an upstream section and a downstream section, a fuel booster, and a heat exchanger is provided. The fuel booster is located in the gaseous fuel supply conduit. The fuel booster has a driving expander with a driving fluid inlet and a driving fluid outlet for discharging expanded air and a fuel compressor with a low pressure fuel inlet connected to the upstream section of the gaseous fuel supply conduit and a high pressure fuel outlet connected to the downstream section of the gaseous fuel supply conduit. The heat exchanger is located between the driving fluid on the one side and the gaseous fuel on the other side so that a heat transfer between the air and the gaseous fuel is possible. | 05-06-2010 |
20100329851 | Inlet Guide Vane for a Gas Compressor - An inlet guide vane for a compressor is provided. The inlet guide vane is adjustable to modify gas flow properties in the compressor, wherein electroactive polymers are arranged in the inlet guide vane such that the shape of the inlet guide vane is adjusted in a specified manner upon applying a voltage to the inlet guide vane. | 12-30-2010 |
20110045416 | Compressor and Method for Compressing Gaseous Fuel - A method for compressing gaseous fuel is disclosed. The method includes, ingesting gaseous fuel into a chamber, ingesting air into the chamber and mixing the gaseous fuel with the air, igniting and partially combusting the resulting mixture of gaseous fuel and air in a confined space such that a predominant fraction of the gaseous fuel is not combusted, causing an increased temperature and therefore an increased pressure of the fraction of the gaseous fuel which is not combusted, and discharging the resulting compressed gaseous fuel. Moreover, a compressor is provided including a casing, a rotor with at least three vanes, an inlet for gaseous fuel, an outlet for gaseous fuel, an air inlet and an igniter. The rotor is placed in the casing such that at least three variable-volume chambers part-bounded by the vanes are formed during a rotor revolution. | 02-24-2011 |
20110082662 | Method and device for detecting capacity changes in a fluid and turbine - A method for detecting capacity changes in a fluid in a flow channel is disclosed. The method includes the steps of leading the fluid to a surface of a defined area, where the heat transfer is enhanced compared with other portions of the flow channel, measuring the temperature of the fluid, heating the surface, recording the power which is supplied during heating the surface, measuring the temperature of the heated surface, determining the heat transfer coefficient of the fluid, and comparing the determined heat transfer coefficient with a reference. Moreover, a device for performing the method and a turbine are provided. | 04-07-2011 |
