摘要:
Die Erfindung betrifft ein Abdeckteil (4) für eine Brennkammer einer Gasturbine, insbesondere eines Gasturbinentriebwerks. Hierbei ist das Abdeckteil (4) eingerichtet und vorgesehen, eine Fluidströmung stromab eines Diffusors der Gasturbine zumindest teilweise in einen Strömungsbereich (12a, 12b) außerhalb eines Brennraums (11) der Brennkammer zu leiten, um eine den Brennraum (11) berandende Brennkammerwand (1a, 1 b) zu kühlen. Ferner weist das Abdeckteil (4) mindestens einen Montagerand (40a, 40b; 421 a, 421 b) auf, an dem wenigstens eine Befestigungsstelle für die Fixierung des Abdeckteils (4) an der Brennkammerwand (1a, 1b) mittels eines separaten Befestigungselements (5) vorgesehen ist. Erfindungsgemäß ist an dem Abdeckteil (4) mindestens ein Leitelement (42a, 42b) im Bereich des Montagerandes (421 a, 421 b) vorgesehen, das im Betrieb der Gasturbine den Teilstrom der Fluidströmung, der in Richtung des Strömungsbereichs (12a, 12b) geleitet werden soll, über einen von dem Montagerand (421 a, 421 b) vorstehenden Teil des Befestigungselements (5) hinweg leitet.
摘要:
The present invention discloses a novel and improved device and method for securing a combustion liner within a gas turbine combustor. The improved configuration comprises a plurality of equally spaced support tab assemblies secured about the combustion liner and positioned radially outward of the combustion zone. The support tab assemblies comprise parallel liner tabs which provide increased flexibility, greater structural support, and lower operating stresses.

An insulation support system for an exhaust gas system gas turbine includes an outer casing 40 having an inner surface 50 and a liner sheet 60 having an inner surface 62 and that defines an insulation gap between the inner surface of the liner sheet and the inner surface of the outer casing. The system further includes a support member 44 that extends from the inner surface of the outer casing to the inner surface of the liner sheet and a threaded fastener 70 that is fixedly connected to one of inner surface of the outer casing or the support member. The threaded fastener has a fixed depth and is aligned with a fastener hole of the liner sheet. The system further includes a bolt 80 that extends through the fastener hole of the liner sheet and threadingly engages with the threaded fastener.

A wall assembly is provided for a gas turbine engine. This wall assembly includes a support shell with a contoured region; and a multiple of liner panels mounted to the support shell. At least one of the multiple of liner panels includes an end rail. The contoured region is deformable to selectively contact at least a portion of the end rail. A method of assembling a wall assembly within a gas turbine engine is also provided. This method includes locating a stud that extends from a cold side of a liner panel through a support shell; and attaching a fastener onto the stud to at least partially close a gap defined between the panel and shell.

A combustor for a gas turbine engine includes an inner combustor wall (104) and an outer combustor wall (106) radially outboard of the inner combustor wall (104). The inner and outer combustor walls define a combustion space therebetween with an upstream inlet (110) and a downstream outlet (112). A combustor dome (102) connects between inner and outer combustor walls at the upstream inlet of the combustion space. The combustor dome (102) includes a plurality of circumferentially spaced apart nozzles and a plurality of tiles (134) mounted to the combustor dome to fluidly separate a downstream side of the combustor dome (102) from an upstream side of the combustor dome (102).

A combustion system (100) for a gas turbine engine includes a combustor dome (102). The combustor dome includes a fuel manifold (118) with an inlet (120) and nozzle components (122) of a plurality of nozzles circumferentially spaced around the combustor dome. The fuel manifold and nozzle components are integrated with the combustor dome for fluid communication from the inlet to the nozzle components.
