Embodiment Construction

[0034] figure 1A steam turbine 1 is shown, which comprises an inner housing 2 and an outer housing 3 as well as a rotor 4 . The rotor 4 is rotatably mounted within the inner housing 2 . The means of support are not shown in detail. The outer casing 3 is arranged around the inner casing 2 . The rotor 4 is substantially rotationally symmetrical about the axis of rotation 5 . Along a first flow direction 6 running substantially parallel to the axis of rotation 5 , the rotor 4 has a high-pressure region 7 . Arranged opposite to the first flow direction 6 , the rotor 4 has a medium-pressure region 9 which is arranged along the second flow direction 8 .

[0035] In the high-pressure region 7 , the inner housing 2 has a plurality of high-pressure guide vanes (not shown), which are arranged on the circumference around the axis of rotation 5 . The high-pressure guide vanes are arranged such that along the first flow direction 6 a high-pressure flow channel 10 is formed with a plur...

Abstract

The invention relates to a steam turbine (1) having a cooling option, in which steam is taken from the flow channel, said steam cooling the thrust-compensating intermediate floor (16), being mixed with a small amount of live steam and being returned to the flow channel.

Description

technical field [0001] The invention relates to a steam turbine comprising an inner casing and an outer casing and a rotor, the rotor being arranged in a rotatable manner within the inner casing, wherein the outer casing is arranged around the inner casing, wherein the rotor has A high-pressure region arranged along the first flow direction and a medium-pressure region arranged along the second flow direction. [0002] Furthermore, the invention relates to a method for cooling a steam turbine, wherein the steam turbine has a high-pressure region and an intermediate-pressure region, wherein a rotor is arranged between the high-pressure region and the intermediate-pressure region and has a thrust-balancing diaphragm. Background technique [0003] Within the scope of this application, a steam turbine is understood to mean a turbine or a turbine section through which a working fluid in the form of steam flows. Unlike here, gas turbines have gas and / or air flowing through them a...
