のレベル制御装置。 In a boiler that supplies steam from the drum of the boiler main body to the steam turbine, condenses the turbine exhaust and surplus steam that bypasses the turbine, and returns the water to the boiler main body via the water supply flow rate control valve, a drum level detector is used. The level detected by the drum, the main steam flow rate detected by the steam pressure detection means, and the water supply flow rate to the boiler main body detected by the feed water flow rate detection means, so that the level of the drum becomes constant. A level control device for a boiler, characterized in that a control system for controlling a control valve includes an addition system for detecting the surplus steam flow rate and adding it to the main steam flow rate.
