Water Levels in Steam Boilers | Spirax Sarco

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…

Optimizing Strategy for Boiler Drum Level Control

Three-element level control as shown in Figure 11 is the most common boiler drum level control strategy. A feedwater flow loop slave is added to the two-element strategy. Three-element level control linearizes the feedwater flow with respect to the steam flow and the level controller output.

2  · 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.
