Problems solved by technology

Since the actuation of the associated nozzle group adjustment is carried out through the corresponding steam seals, losses of steam are unavoidable in this case, and can be particularly large when passing through several steam seals

Embodiment Construction

[0027] The same components are provided with the same reference numerals in all figures.

[0028] figure 1 The steam turbine device 2 includes a steam turbine 4 and a generator 6 connected thereto, and includes a condenser 10 and a steam generator 12 arranged downstream of the steam turbine 4 in a water-steam cycle 8 . The steam turbine 4 consists of a first pressure stage or high pressure section 4 a and a further stage or medium and low pressure sections 4 b , which drive a generator 6 via a common shaft 14 .

[0029] The steam generator 12 is connected on the steam outlet side to a steam inlet 18 of the high-pressure part 4 a of the steam turbine 4 . The steam outlet 20 of the high-pressure part 4a of the steam turbine 4 is connected via an overflow line 22 to the steam inlet 24 of the medium-pressure and low-pressure part 4b of the steam turbine 4 . The steam outlet 26 of the medium-pressure and low-pressure part 4b of the steam turbine 4 is connected to the condenser 10...

Abstract

The inventive steam turbine installation (2) is equipped with a steam inlet valve (38, 42) which has a particularly good regulation capacity and which therefore keeps steam (D) losses especially low, in order to control the introduction of steam (D) into a steam collecting chamber (40, 44). The steam inlet valve (38, 42) has a rotary cylinder (64) for this purpose. Said rotary cylinder (64) is located in a housing (52) and serves as a shut-off element. A steam inlet (54) can be connected to a steam outlet (56) by a channel (80) provided in the surface (66) of the rotary cylinder (64).

Description

technical field [0001] The invention relates to a steam turbine device. A steam collecting box is arranged upstream of the steam turbine, wherein a steam inlet valve is arranged to control steam entering the steam collecting box. Background technique [0002] Steam turbine installations are often used to generate electrical energy or drive process machinery. The working fluid (usually a water-water / steam mixture) operating in the evaporator cycle of the steam turbine unit is vaporized in the evaporator. The steam produced is expanded in a steam turbine to perform work, and is then fed into a condenser or process machinery. The working fluid condensed in the condenser is then re-supplied into the evaporator by means of a feed water pump. [0003] In steam turbine installations, regulating valves called nozzle bank regulators are used to control the entry of steam into the header. The opening and closing of the control valve is usually carried out by means of a spindle syst...
