Plant Engineering | Maintaining boiler safety

The water level is critical to ensure a flooded supply of water to downcomer tubes (Fig. 3). Because sufficient water level is critical modern boilers are equipped with automatic low-water trip switches. Some older boilers may not have these relatively inexpensive devices. If a boiler does not have low-water trips have these devices installed.
