Abstract

PURPOSE:To reduce incurring of starting loss and to improve the efficiency of a load regulating operation and the like, by a method wherein a turbine for driving a water feed pump is started by means of steam from other unit, and after, after ignition of a boiler, generated steam is increased enough in temperature and pressure, steam is extracted from the boiler. CONSTITUTION:During the starting of a plant, steam from other unit is fed to a water feed pump turbine 26 through an auxiliary steam header 28. This starts a water feed pump 37, and starts the feed of water to a boiler 31. After ignition of the boiler 31, after boiler generation steam is increased in temperature and a pressure to a value being high enough to allow driving of the water feed pump turbine 26, boiler generation steam is fed to the water feed pump turbine 26 through a steam line 27 for starting from the outlet of a heat transfer pipe 35 at the rear of a ceiling, and is switched to steam from an auxiliary steam header 28. This reduces incurring of starting loss and performs efficient load regulating operation.
