Steam power plant for generating electrical energy

摘要

A steam power plant is provided. The steam power plant includes a bypass pipeline which connects the fresh steam line flow to the exhaust steam line, wherein a bypass steam cooler is disposed in the bypass pipeline. In the event of an emergency stop, or a startup, or a shutdown, the bypass steam cooler cools the steam flowing into the bypass pipeline, whereby cheaper materials may be used for the bypass pipeline.

主权项

1. A steam power plant for generating electrical energy, comprising:
a steam turbine; a steam generator; a condenser; a live steam pipeline which fluidically interconnects the steam turbine with the steam generator; an exhaust steam line which fluidically interconnects the steam turbine with the condenser; a bypass pipeline which fluidically interconnects the live steam pipeline with the exhaust steam pipeline,wherein provision is made in the bypass pipeline for a bypass-steam cooler, which is designed for cooling steam which flows in the bypass pipeline; and a high-pressure bypass valve included in the bypass pipeline, and wherein the bypass-steam cooler is arranged downstream of a first branch from the live steam pipeline on the bypass pipeline, and wherein the bypass-steam cooler is arranged between the first branch and the high-pressure bypass-valve.
