Each of the swirler arrangements includes an air swirler and a pre-combustion chamber disposed downstream of the air swirler, and a longitudinal axis of each swirler arrangement intersects a line parallel to, and spaced apart from, the longitudinal axis of the shell. The swirler arrangements are preferably connected to the shell at the same axial point. | 06-04-2009 |
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 |
20090320490 | Gas Turbine Combustor - A gas turbine combustor is provided, which comprises: a combustion chamber having an axial direction and a radial direction; air passages for feeding an air stream into the combustion chamber which are oriented such that the flowing direction for each air stream flowing into the combustion chamber includes an angle with the combustion chamber's radial direction so as to introduce a swirl in the in-flowing air and an angle of at least 60° with the combustion chamber's axial direction; and fuel injection openings which are located in the air passages. Each air passage defines a turning flow path with a turning between 70° and 150° in a radial direction of the combustion chamber and a turning between 0° and 235° in an axial direction of the combustion chamber. | 12-31-2009 |
20100011779 | TURBINE WITH FLUIDICALLY-CONTROLLED VALVE AND SWIRLER WITH A BLEED HOLE - A fluidically-controlled valve is provided. The fluidically-controlled valve includes a main flow channel with a main flow entrance, a flow exit and a constricted channel section located between the main flow entrance and the flow exit. The fluidically-controlled valve also includes a control flow channel including a jet forming control entrance, a first branch channel, a second branch channel, a common channel section, and a convex channel wall. The common channel section follows the control entrance, the first branch channel emerges from the common channel section and leads to the main flow entrance, the second branch channel emerges from the common channel section and leads to the constricted channel section, and the convex channel wall extends from the common channel section into the first branch channel. The fluidically-controlled valve can be used in bypasses present in turbines or in swirlers of gas turbine combustors. | 01-21-2010 |
20100089468 | FLOW DISTRIBUTION REGULATION ARRANGEMENT WITH BIMETALLIC ELEMENTS FOR ADJUSTING THE FLOW DISTRIBUTION IN A COOLING CHANNEL - A flow distribution regulation arrangement in a cooling channel is provided. The flow distribution regulation arrangement includes a plurality of bimetallic elements adapted to adjust a local flow of a cooling medium in the cooling channel in response to a heat load onto the bimetallic elements, wherein the heat load originates from local boundary sub areas of the cooling channel. | 04-15-2010 |
20100104432 | ARRANGEMENT FOR A GAS TURBINE ENGINE - An inlet guide vane arrangement for a gas turbine is provided. The arrangement includes a plurality of guide vane duct elements, the guide vane duct elements include a suction side wall and a pressure side wall, both walls facing each other, and are designed to be adjoinable to another of the guide vane duct elements, such that the pressure side wall of one guide vane duct element cooperates with the suction side wall of the adjacent guide vane duct element thereby forming a guide vane. The guide vane duct element includes features to accept a key element adapted to be arranged between the pressure side wall and the adjacent suction side wall, when two guide vane duct elements are adjoining to one another, and to attach together both adjoining guide vane duct elements. | 04-29-2010 |
20100162710 | Pre-Mix Combustion System for a Gas Turbine and Method of Operating of operating the same - The invention is related to a gas turbine pre-mix combustion system comprising: at least one combustor with a combustor wall partly surrounding a combustion zone; at least one mixing duct including an air passage leading to an outlet opening being open towards the combustion zone; and one or more fuel injection openings leading into the air passage and connecting it to one or more fuel supply passages so as to allow the injection of fuel into air flowing through the air passage. The locations of at least two outlet openings or at least two sections of a single outlet opening and the orientation of downstream sections of the respective air passages or air passage are chosen such that fuel/air mixtures flowing out of the outlet openings or said sections of a single outlet opening show opposed flow paths so as to impinge on each other in the combustion zone. | 07-01-2010 |
20110011054 | COMBUSTOR CASING - A combustor casing with an inner casing and an outer casing and a bimetallic element arranged on an inner side of the inner casing is provided. The inner casing includes a pre-chamber area, where combustion is initiated in a fuel rich state, with an upper end and a lower end, the upper end sized and configured to be connected to a burner head. The bimetallic element is located within the pre-chamber area. | 01-20-2011 |
20120144833 | Arrangement for Preparation of a Fuel for Combustion - An arrangement for preparation of a fuel for combustion including a burner is provided. The arrangement includes a combustion chamber associated with the burner and in which combustion of a fuel is to take place, as well as means for supplying liquid fuel to the arrangement through an internal passage in the burner for the combustion, solid portions of the burner body being heated by the combustion, wherein the internal passage is located inside the solid portions of the burner body for receiving heat energy evaporating the fuel from these body portions, and that it includes means for conveying vaporized fuel to the combustion chamber to take part in the combustion. | 06-14-2012 |
