Water Level Control For Boiler

Boiler Safety and Role of Low Water Levels

Also when the fresh water is added from the feedtank it cools the drum water, leading to collapse of the steam bubbles and an immediate drop in the water level. To overcome this shrink and swell effect in boiler one may opt for a 3 level drum control.
