Claims

[Scope of utility model registration request]

A boiler water supply control system in which the water supply flow rate to the boiler is controlled from three elements: drum level, main steam flow rate, and feed water flow rate, characterized in that the feed water flow rate signal is delayed through a delay element. control system.
