Abstract

PURPOSE: To minimize the flactuation in a main feeding water at the time of changing-over, by changing-over a pump at the time when the main feeding water volume comes to the sum of the volume exceeding 1/2 of the rated discharge of a motor driven water feeding pump and the volume exceeding water feeding discharge at the time of a minimum flow valve of a turbine driven water feeding pump being fully closed.
