Definitions
- the invention relates to a steam power plant according to the preamble of claim 1.
- Such a steam power plant is known from DE 196 42 100 A1.
- the order of the capacitor inside the machine house leads to widening of the nacelle by several meters, resulting in a corresponding enlargement the span and the installation height of the nacelle crane. For cost reasons the widening is carried out as little as possible, so that an optimization the construction of the condenser neck to contribute to an improvement in efficiency of the power plant is restricted.
- With arrangement of turbine and Condenser on the same foundation is a return flow of the condensate to low pressure turbines not secured and a higher head of the main cooling water pumps expected.
- the condensate storage of the capacitor can only be done by one Special construction for the purpose of drainage of those in vacuum Components can be used directly.
- DE 196 42 100A1 is the center line of the capacitor arranged above the turbine center line. This creates an unfavorable flow behavior and a higher flow deflection Pressure loss.
- An additional drainage device for the low-pressure turbine housing is required, which with an increase in the height of the upper part of the Low pressure turbine housing and thus a corresponding increase in the nacelle goes along.
- the task is to specify a steam power plant of the type mentioned at the beginning, which leads to a nacelle that is reduced in height and width and still brings no restriction in the design of the condenser neck.
- the condenser with its inlets and outlets for the main cooling water is then in an extension of a nacelle arranged.
- the construction volume of the machine house can be reduced.
- the length of the condenser neck can be freely due to its arrangement in one expandable extension, regardless of the nacelle height and width become.
- Over the entire cross-section of the outflow of the condenser neck is an even inflow field ensured.
- the arrangement ensures an optimal definition of the diffuser angle ⁇ , which influences the flow behavior in the condenser neck. In such a way optimally designed condenser neck, the steam flow is low loss to a lower speed with simultaneous pressure recovery delayed.
- the Condenser neck has a predeterminable gradient in the direction of the condenser, the The condenser centerline is located below the turbine centerline.
- Figures 1 and 2 show a turbo group 1 of a steam power plant, not shown, which are supported on a foundation plate 2 insulated from the nacelle 3 is.
- An extension 4 borders the machine house 3. From the machine house and extension only the supporting structure is shown, to take a look at the arrangement of those inside Components.
- the cultivation can depend on the climatic conditions as a complete enclosure, only with a roof or in open-air construction be trained.
- the machine house is in the longitudinal direction 3 aligned the turbo group 1 and fixed relative to the nacelle.
- An exhaust steam flow leaving the low-pressure part of the turbine 10 via an outlet housing 5 passes through a condenser neck 6 acting as a diffuser to an im Attachment 4 arranged condenser 7.
- An inlet and outlet 8, 9 for the main cooling water is connected to pipes, not shown.
- the condenser neck bridges the distance between the condenser 7 and the outlet housing 5 and penetrates the wall 11 between the extension 4 and the nacelle 3. How 2, the condenser neck 6 points in the direction Condenser 7 acting gradient, which is so large that a condensate return to the turbine is safely avoided.
- the center line 13 of the capacitor 7 is located below the turbine centerline 12 to e.g. B. a reflux of the condensate to ensure the low pressure turbines. Due to the lateral arrangement of the Capacitor 7 results in a low construction of the turbo group and thus also a correspondingly lower engine house. Furthermore, an optimal one Definition of the diffuser angle ⁇ , which is the flow behavior in the condenser neck influenced, guaranteed. To improve the efficiency of the steam power plant can be the length of the condenser neck for optimal design of the condenser diffuser can be easily changed.
