Research on Problems of Steam Drum Liquid Level Control of Evaporative Cooler for Heating Furnace

Poor liquid level control occurred in evaporative cooler for heating furnace of a hot rolling plant in Shanxi.For this reason,the important significance of the level control was discussed.Selection of steam discharge point,selection of liquid level gauge and selec-tion of level regulation system were analyzed,so as to improve level control effect and to guarantee safety and routine operation of the evaporative cooler.
