するボイラ給水制御装置。In the boiler feed water control system, the reverse response phenomenon of the drum level is detected from changes in the monotonous pressure, drum level, and main steam flow rate in the three-element control output calculated from the main steam flow rate, feed water flow rate, and drum level signal. A boiler feed water control device characterized in that the feed water amount is controlled by adding a difference between a steam pressure signal and a set value at the time of a reverse response.
