Steam Boiler Water Level Control

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. If, however, there is a high demand for steam from this boiler, the rate of evaporation will be much greater.

Water Levels in Steam Boilers

In horizontal shell boilers, the water level rises with increasing load (due to the presence of more steam being below the water level in the boiler). As it does so, the water surface area (steam release area) will decrease because, as the water level is above the centre line of the boiler, the sides of the containing shell converge.

Web Exclusive: Boiler feedwater control

Single element drum level control measures drum level only. This is a simple feedback control loop (Figure 1). The mass of the water flow and the steam flow must be regulated so mass water flow equals the mass steam flow to maintain drum level. The feedwater control regulates the mass water flow to the boiler.
