  • BOILER CONTROLS - tpub.com

    The control element depends on the water level in the boiler steam drum. Thus, a certain water level in the drum corresponds to a certain opening of the feedwater control valve. The float type of feedwater regulating and low-water cutoff controls are used on water-tube and fire-tube boilers designed for semiautomatic or automatic operation.

    If there isn't much steam being drawn off the boiler, this means there will be little water boiled into steam and therefore little need for additional feedwater to be pumped into the boiler. Therefore, in this situation, one would expect the control valve to hover near the fully-closed position, allowing just enough water into the boiler to keep the steam drum water level at setpoint.
