Automatic Level Control Systems | Spirax Sarco

If the demand for steam increases, the pressure in the boiler initially falls, and the control system will increase the burner firing rate. The rate of evaporation will increase to meet the increased demand. The increased rate of evaporation means that the boiler water will contain more steam bubbles and become even less dense.
