Abstract
PURPOSE: To prevent occurrence of water hammering action, by providing a water supply pipe for filling up cooling water always in a water chamber formed in an attemperator in a steam feeding line and also in a piping for connecting the water chamber and a rapid opening valve in a cooling-water feeding line.
CONSTITUTION: A turbine by-pass system of this invention comprises a line for carrying steam extracted from a main steam line to an attemperator vai a high- pressure by-pass valve (not shown) and a low-pressure by-pass valve 14 and then feeding the steam to a condenser 10 after lowering the pressure and the temperature of steam in the attemperator 15 and another line for carrying cooling water branched from an outlet pipe of a condensate pump to a water chamber 18 of the attemperator 15 via a rapid opening valve 16 and a piping 17. Here, a by-pass pipe 19 having an orifice 20 is provided in the manner of by-passing the rapid opening valve 16. Since, with such an arrangement, cooling water can be always filled in piping 17 via by-pass pipe 19 even if rapid opening valve 16 is closed, it is enabled to ensure safe operation by preventing occurrence of water hammering action at the time when the rapid opening valve 16 is opened.
