Problems solved by technology

While this damage can be minimized by using corrosion resistant materials, this is very expensive and can lead to the need to renew the material in the event of later maintenance
[0010] The hitherto configuration of perforated cages and discharge pipes is such that an after-expansion occurs in which the merging of the beams from the individual apertures (which may be referred to as throttled apertures) occurs and thus a large continuous flow with supersonic flow occurs. areas in which there is a potential risk of damage

Embodiment Construction

[0033] figure 1 A condenser 1 is shown. The condenser 1 includes a condenser shell 2 and a condenser tube 3 . The cooling medium flows through the condenser pipe 3 . The steam delivered from the low-pressure sub-turbine into the condenser shell 2 condenses into water at the surface of the condenser tube 3 . exist figure 1 The delivery of steam from the low-pressure sub-turbine to the condenser 1 is not further shown in .

[0034] In bypass operation, steam with high energy flows via the steam bypass system via the bypass line 4 through the condenser housing 2 into the component 5 , in this case a perforated cage 6 . A reinforcing element 7 is arranged in the condenser 1 . Assembly 5 includes a housing 8 configured to restrict flow from bypass line 4 .

[0035] The housing 8 has a plurality of holes 9 . The assembly 5 and the housing 8 are configured such that steam from the bypass line 4 can only flow into the condenser interior through the holes 9 and no steam can esca...

Abstract

The invention relates to an arrangement (5) for making a flow uniform, having a housing (8), which is designed to limit the flow, wherein the housing (8) has holes (9) through which the flow flows, asa jet, into a space outside the housing (8), and the holes (9) are spaced apart in such a way that it is not possible for jets coming from two adjacent holes (9) to merge.

Description

technical field [0001] The invention relates to a steam bypass system for introducing a flow consisting of energy-rich steam into a condenser, the steam bypass system comprising an assembly for equalizing the flow, wherein the assembly has a housing which is enclosed by The flow-limiting configuration is such that the housing has a plurality of openings through which the flow flows as jets into the space outside the housing. Background technique [0002] In steam turbine installations, steam is generated in so-called steam generators and is conducted via lines to the steam turbine. The thermal energy of the steam is converted into mechanical rotational energy in the steam turbine. Here, the pressure and temperature of the steam decrease. After the steam has passed through the steam turbine, the steam flows at relatively low temperature and pressure into a condenser, where the steam condenses on cooled condenser lines and is converted back into water. [0003] Operating me...
