御装置。In a level control device for a drum type boiler, the level of the drum is controlled by adjusting the feed water flow rate using a set value obtained by adding a correction to the drum level signal of the boiler using a drum pressure signal and a main steam flow rate signal. Set the steam flow rate signal to -H -) 1. A level control device for a boiler, characterized in that an output obtained by entering a J-mitter or the like and subjected to phase compensation is used as a correction signal when adjusting the water supply flow rate.
