Process of removing water-soluble impurities from the working medium of a steam power plant

摘要

A process of removing water-soluble impurities from the working medium of a steam power plant is disclosed. Steam is bled from a high-pressure turbine downstream of the Wilson Line region. The steam is partially condensed, so that impurities in the steam are carried by the condensate. Moisture separators are disposed in the feed lines connecting the bleed lines with various heaters and the like. The bleed steam is supplied to the various heaters to heat the boiler feedwater and the working fluid of the turbine. The drains of the moisture separator are connected to a purification tank to remove the impurities from the condensate.
