  • Patent number: 7681396
    Abstract: A steam turbine (10) with heating steam extraction includes a plurality of turbine sections (11, 12, 15, 17, 19, 20) for the high pressure, medium pressure and low pressure ranges, which turbine sections (11, 12, 15, 17, 19, 20) are arranged in each case in a separate casing and connected by a common shaft (28), and which includes one high pressure turbine (11), at least one subsequent medium pressure turbine (15, 17), which is connected on the outlet side to two series-connected heaters (21, 24) of a district heating circuit (27), and one subsequent low pressure turbine (19, 20). Safe control of high volumetric flows of steam is achieved by providing, for heating steam extraction, two medium pressure turbines (15, 17), which operate in parallel, in separate casings, and which are connected on the outlet side in each case to one of the heaters (21, 24).
