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

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.
