摘要

The arrangement has high, medium and low pressure steam cylinders (HPT, IPT, LPT), which are connected with one another over a steam circuit. The cylinders (IPT, LPT) are provided along a combined shaft (W) that is impelled with rated speed dependent on the generator. A high-pressure steam cylinder (VHPT), connected with the steam circuit, is provided on a separate shaft (WS) that is directly connected to a compressor unit (V). The high pressure steam cylinder has a flow channel that is designed based on the speed of the shaft.
