Title
(EN) COMBUSTION CHAMBER WITH A CERAMIC FIRE TUBE
(FR) CHAMBRE A COMBUSTION A TUBE A FEU EN CERAMIQUE
Abstract
(EN)
The invention relates to the field of power engineering and can be used in the aircraft and automobile industries as well as in power engineering. It ensures that the fire tube and the housing of the combustion chamber in a gas-turbine engine are thermally isolated from one another. The combustion chamber has a ceramic fire tube (5) mounted within the housing (1), there being a ring-shaped space (6) between the two elements. The fire tube (5) is formed by a series of consecutive ceramic ring-shaped elements (7), each of which has end sections (8, 9) with conical outer and inner surfaces as appropriate and is configured in relation to the housing and the adjacent ceramic ring-shaped element so as to leave a gap (10) along the line of the axis between the conical surfaces and the heat barriers (14) arranged in the gaps (10) between the end sections (8, 9) of the ceramic ring-shaped elements (7). The fire tube (5) is secured within the housing (1) by a shell (11) inside the ring-shaped space (6), the shell being secured to the housing (1), connected to the heat barriers (14) and forming a ring-shaped gap (18) with the outer surface of the ceramic ring-shaped elements (7) and ring-shaped chambers (19) enclosing the heat barriers (14) and communicating with the fluid medium source and with the gaps (10) between the conical surfaces of the ceramic ring-shaped elements (7). With this design, there is no direct thermal contact between the ceramic ring-shaped elements, the shell and the combustion chamber housing.

L'invention concerne le domaine des techniques de production d'énergie et peut être utilisée dans les industries de l'aéronautique et de l'automobile ainsi que dans des techniques de production d'énergie. Elle assure que le tube à feu et le logement de la chambre de combustion dans un moteur à turbine à gaz sont isolés thermiquement l'un de l'autre. La chambre de combustion présente un tube à feu en céramique (5) monté à l'intérieur du logement (1), un espace (6) de forme annulaire séparant les deux éléments. Le tube à feu (5) est constitué d'une série d'éléments (7) en céramique consécutifs de forme annulaire, dont chacun présente des parties terminales (8, 9) comportant, selon le cas, des surfaces extérieures et intérieures coniques et est configuré par rapport au logement, ainsi qu'à l'élément de forme annulaire en céramique adjacent, de manière à laisser un espace (10) le long de l'axe situé entre les surfaces coniques et les barrières thermiques (14) agencées dans les espaces (10) entre les parties terminales (8, 9) desdits éléments de forme annulaire en céramique (7). Le tube à feu (5) est fixé à l'intérieur du logement (1) par une enveloppe (11) à l'intérieur de l'espace annulaire (6), l'enveloppe étant fixée au logement (1), reliée aux barrières thermiques (14) et formant un espace annulaire (18) avec la surface extérieure desdits éléments annulaires en céramique (7) et les chambres annulaires (19) renfermant les barrières thermiques (14) et communiquant avec la source de milieu fluide ainsi qu'avec les espaces (10) situés entre les surfaces coniques desdits éléments annulaires en céramique (7). Cette conception ne présente pas de contact thermique direct entre les éléments annulaires en céramique, l'enveloppe et le logement de la chambre de combustion.
