Steam power plant

Abstract

A steam power plant including a number of partial turbines is provided. Each partial turbine is permeated by steam, an overflow line disposed between a first partial turbine and a second partial turbine and an intermediate superheater in the overflow line. A bleeder line for extracting steam is thereby fluidically connected to the first partial turbine after the expansion stage, prior to the intermediate superheater. An expansion device is further provided, into which the bleeder line opens, and a consumer is connected via a process steam line of the expansion device.
