Abstract:
Die vorliegende Erfindung betrifft eine Brenneranordnung für eine Gasturbine mit wenigstens einer Brennkammer, mit einem zentral angeordneten Pilotbrenner und mehreren den Pilotbrenner umgebenden Hauptbrennern (107), wobei jeder der Hauptbrenner (107) ein zylinderförmiges Gehäuse (12) mit einer darin zentral angeordneten, einen Brennstoffkanal (16) für flüssigen Brennstoff aufweisenden Lanze umfasst, wobei die Lanze über Drallschaufeln (17) am Gehäuse (12) abgestützt ist und in Richtung der Brennkammer ein Aufsatz (13) an der Lanze angeordnet ist, wobei mindestens eine Flüssigbrennstoffdüse in dem Aufsatz (13) vorzugsweise stromab der Drallschaufeln (17) angeordnet und mit dem Brennstoffkanal (16) verbunden ist. Zur verbesserten Durchmischung des Brennstoffs mit der Luft ist die mindestens eine Flüssigbrennstoffdüse als Vollstrahldüse (1) ausgestaltet und die mindestens eine Vollstrahldüse (1) weist eine Länge und einen Durchmesser auf, wobei das Verhältnis Länge zu Durchmesser mindestens 1,5 ist.
Abstract:
A burner assembly (6) is provided comprising a support housing (25) with a supply manifold (27) comprising a fuel passage system (49, 51, 53, 55, 57) and with fuel nozzles (29) extending from the supply manifold (27) and being supplied with fuel through the fuel passage system (49, 51, 53, 55, 570) of the supply manifold (27, 127). The supply manifold (27) is sandwiched from at least two subparts (37, 39, 41).
Abstract:
A method for manufacturing a heat transfer design for progressive htc cooling channel arrangements for a region of a gas turbine engine is provided. The 5 method includes generating a non-transitory computer-readable three-dimensional (3D) model of the cooling channel, which includes cooling sections adapted for use in component with various component regions, with some sections having cooling flux mitigation adaptations to overcome the effects of increased temperature in the component regions to maintain efficient cooling effectiveness throughout the cooling channel sections. Adaptations may include regions of cross sectional area that increases heat transfer effectiveness, as well as regions characterized by an increase in lateral flow compared to longitudinal flow.
Abstract:
An improved interface (111) between a combustion basket ring and a transition assembly (113) in a can-annular gas turbine engine. Traditionally, a spring clip is positioned within a circumferential gap between a combustion basket ring and the transition assembly such that a gas flow across the interface experiences a radial offset based on the circumferential gap. The improvement includes a flared inlet end (140) of the transition duct (114) to eliminate the radial offset of the gas flow (116) across the interface (111). A transition assembly (113) is provided including a transition inlet ring (120) and the transition duct (114) with the flared inlet end (140).
Abstract:
A trailing edge duct (110) is used with gas turbine engines. The trailing edge duct (110) is unitary in shape and has improved aerodynamics. The trailing edge duct (110) has a trailing edge (120) that is able to provide improved support and structural integrity as compared to previous ducts used in converging flow junctions. An extension flange (115), which forms part of the trailing edge (120) has clearance holes (113) formed therein that permit easy maintenance.
Abstract:
An assembly for a gas turbine is presented. The assembly includes a gas supply pipe passing through a bore in a flange of the gas turbine for supplying gas to a combustion chamber of the gas turbine and a sleeve surrounding the gas supply pipe, having a first end and a second end, wherein the first end is sealingly coupled to the gas supply pipe, and wherein the sleeve is adapted to be sealingly coupled to the flange at the second end such that the sleeve extends along a thickness of the flange.
Abstract:
The present invention explains a multi-fuel combustion system. It consist of a combustor basket adapted to combust at least two type of fuels. The combustor basket has got a circumferential wall comprising a plurality of openings. The combustion system further has a first conduit adapted to provide a first type of fuel directly to the combustor basket, a second conduit adapted to provide a second type of fuel directly to the combustor basket. Optional the combustion system has a third conduit adapted to inject at least one of the first type of fuel and the second type of fuel through the openings into the combustor basket.
