Abstract: A machine train includes a drive unit, preferably a steam turbine with axial exhaust flow, a geared turbine machine, and an additional compressor. The geared turbine machine has an integrated gear train with a drive pinion for driving turbine machine rotors via a large gear, and an output pinion of a rotational speed reduction power gear for driving the additional compressor.

Abstract: An intercooler (3) is provided with heat exchanger surfaces (6) and is arranged in the gas stream between two compressors (1, 2) or two compressor stage groups for compressing a gas. An aftercooler (5) is also provided with heat exchanger surfaces (7) and is arranged after the second compressor (2). To utilize the waste heat generated in the coolers (3, 5), the heat exchanger surfaces (6, 7) of the intercooler (3) and of the aftercooler (5) are integrated in a steam generator (9) in such a way that the heat exchanger surfaces are connected with the feedwater pump (40, 59) of the steam generator (9).

Abstract: A axially split casing with flange connection of two casing halves, wherein the casing upper part (1) is bolted to the casing lower part (2) with split line bolts (5) on the circumference of the axial split line flange (3). An axially divided casing extension (9), which is surrounded by a coaxially arranged axially unsplit ring (11) on the outer circumference, is arranged at one or both end faces (4) of the casing upper part (1) and the casing lower part (2) in the area of the casing axis (8). Wedge-shaped tensioning elements (14), which are tensioned by means of tension bolts (15) between surfaces (13) arranged in the ring (11) and countersurfaces (12) of the collar (10) of the casing extension (9), may be additionally arranged between surfaces (12, 13) arranged in the ring (11) and the collar (10) of the casing extension (9).
