Abstract: The combustion device (1) of a gas turbine includes burners (2) connected to a front plate (5) of a combustion chamber (3). The front plate (5) has, spaced apart from one another, a front sheet (8) and an impingement sheet (7) with aligned holes (11, 12) housing the burners (2). A piston ring (15) is provided between the front sheet (8) and impingement sheet (7) to seal the holes (11, 12). The axial length of the border of the hole (11, 12) of the front sheet (8) and/or impingement sheet (7) is longer than the thickness of the corresponding front sheet (8) and/or impingement sheet (7).

Abstract: A method of dismantling a turbomachine includes opening a turbomachine casing in the region of a combustion chamber, releasing a top half shell from a bottom half shell, axially displacing the top half shell and thereafter removing the top half shell in essentially the radial direction, rotationally fixedly connecting an auxiliary tool to the rotor of the turbomachine, connecting the auxiliary tool to the bottom half shell via axially displaceable adapter slides arranged on said auxiliary tool, axially displacing the bottom half shell to release the bottom half shell from axial connecting contours, rotating the bottom half shell with the rotor by approximately 180° until the bottom half shell assumes essentially the position of the removed top half shell, and releasing the bottom half shell and removal of said bottom half shell.

Abstract: A turbomachine (2) has a combustion chamber (1), in particular a gas turbine, with a casing (8) which has a closable maintenance opening at least in the region of the combustion chamber (1), which maintenance opening, in the open state, provides access to an outer carrier (3), an inner segment carrier (5), and a front plate (4), which together define the combustion chamber (1). In order to simplify the maintenance of the turbomachine (2) and thereby reduce any downtimes and maintenance costs, the outer carrier (3), the inner segment carrier (5) and the front plate (4) are designed as annular shell elements (13) having a respective bottom half shell (14) and a respective top half shell (15) which can be connected thereto. In the assembled state, the outer carrier (3), the inner segment carrier (5), and the front plate (4) are connected to one another and/or to the casing (8) via connecting contours (7) which are axially releasable from one another.
