Bypass steam line

Abstract

The invention relates to a mixing unit (1) for mixing water with steam in a bypass station, wherein a plurality of Laval nozzles (5, 5a, 5b,...) are arranged in the mixing unit (1), which Laval nozzles (5, 5a, 5b,...) are displaced axially with respect to one another in a water steam direction, with the result that the noise emissions are reduced overall.

Description

technical field [0001] The invention relates to a mixing unit for mixing a flow medium with a cooling medium, said mixing unit comprising a tube channel section to which the mixing section is fluidically coupled, wherein the mixing section comprises a plurality of The Laval nozzle through which the flow medium can flow, wherein injection channels are formed in the Laval nozzle, through which the cooling medium flows, so that mixing of the flow medium and the cooling medium takes place. Background technique [0002] In a steam power plant, steam is generated in a steam generator, which converts the thermal energy of the steam into rotational energy in a turbine unit fluidly coupled to the steam generator. Rotational energy is eventually converted into electrical energy. As long as the steam power plant is running in continuous operation and the load on the generator is relatively constant, the thermodynamic performance is relatively constant in time. [0003] There are ofte...

Furthermore, it has been shown that the temperature distribution is not sufficiently homogeneous, which leads to suboptimal operating behavior at partial loads
