  • 6.1 Example: boiler water level control system

    An important variable to measure and control in a continuous boiler is the level of water in the "steam drum" (the upper vessel in a water-tube boiler). In order to safely and efficiently produce a continuous flow of steam, we must ensure the steam drum never runs too low on water, or too high.

  • Boiler – level control, high and low water limitation |

    The size of the steam generator is what determines the quantity of saturated steam that can be fed into a heat exchanger. Reliable control of the water level and limitation of high and low water levels are therefore extremely important. In power plants boilers are governed by the steam pressure and the process temperature.
