    摘要: A helicoidal structure promotes cooling of a liner (1250) applied in an annular space of a double-shell structure formed of the liner (1250) and a flow sleeve (1270) to cool a duct assembly, by increasing the residence time and cooling area of cooling compressed air (A) on the surface of the liner (1250). The helicoidal structure includes a helicoidal rib (100) protruding from a surface of the liner (1250) to guide the cooling compressed air (A) at a predetermined angle with respect to an axial direction of the liner (1250), the helicoidal rib (100) having cooling holes (200) and forming a first cooling passage (310) along which main-cooling compressed air flows and a plurality of secondary cooling passages (320) along which auxiliary-cooling compressed air flows. The plurality of secondary cooling passages (320) induces a flow of the auxiliary-cooling compressed air through the cooling holes (200), and the flow of the auxiliary-cooling compressed air is derived from a flow of the main-cooling compressed air in the first cooling passage (310).

    摘要: A combustor (10) is provided and includes a liner (20) through which fluid fed from at least two injection points flows from a head end (22) to an interior of a transition piece (23), a first one of the at least two injection points being axially proximate to a fluid impenetrable coupling (50) between the liner (20) and the transition piece (23) and defining apertures (60) disposed in fluid communication with a first passage (35) leading to the head end (22), and a second one of the at least two injection points being disposed axially between the apertures (60) and the head end (22) and upstream from the apertures (60) relative to a direction of fluid flow through the first passage (35), the second one of the at least two injection points being formed of openings (100) disposed in fluid communication with a second passage (45) leading to the head end (22).

    摘要: The invention relates to a combustion chamber housing (10) and to a gas turbine (1) equipped therewith, wherein the combustion chamber housing has a flame tube (20) and a cladding tube (30) which surrounds the flame tube and which in the wall thereof has a plurality of through-holes (31) via which air flowing on the outside onto the cladding tube can radially penetrate into an intermediate space (40) formed between the cladding tube and the flame tube. The invention assures uniform distribution of the inflowing air around the flame tube. This is achieved, among other things, by providing a plurality of guide ribs (50), which are distributed in the intermediate space on the circumference of the two tubes and which each extend radially between the cladding tube and flame tube and parallel to a longitudinal direction (LR) of the two tubes such that the intermediate space is divided by the guide ribs into several longitudinal channels (41).
