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: In a method for the combustion of a fuel, a fuel or a premixed combustible mixture is introduced into a combustion space as a combustible fluid open jet. The velocity of the open jet is selected in such a way that it is impossible for a stable flame front to form, i.e. is in any event greater than the flame front velocity, and that, on account of a jet pump effect, flue gas is mixed into the combustible fluid jet from the combustion chamber in a jet-induced recirculation internally within the combustion chamber. The admixed flue gas dilutes and heats the combustible fluid. The heating causes the spontaneous ignition temperature to be exceeded, and a low-pollutant volumetric flame is formed in a highly dilute atmosphere.

Abstract: A combustion chamber 10 for a gas turbine that operates in a highly diluted mode of combustion has a substantially toroidal plenum 30. At least one combustion fluid injector is located at the periphery of the plenum. The shape of the plenum and the disposition of the combustion fuel injectors are such that a vortex flow 2 is established in the combustion chamber in use. Gasses are entrained in the vortex which provides high enough levels of flue gas re-circulation to allow for the onset of highly diluted combustion.

Abstract: A gas turbine adapted to operate in a highly diluted mode comprises a compressor 3 adapted to compress oxidant 5; a combustion chamber 3 adapted to accept the compressed oxidant 7 and provide an exit means for flue gas 9; a turbine 4; and a flue gas re-circulation means 12,13 adapted to re-circulate the flue gas 9 from the combustion chamber 3 and mix the said flue gas with the compressed oxidant 7 from the compressor 2 in order to provide a highly diluted mode of combustion with a flue gas re-circulation rate of from 100% to 200%.

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.

Abstract: The invention relates to a process, in particular for a process for generating electrical power and/or heat, in which a gas mixture is formed from oxygen, fuel and substantially nitrogen-free inert gas and is burnt in a burner (3). In order to ensure stable combustion even in the case of a relatively high amount of inert gas, the combustion is embodied as flameless combustion.
