Boiler Drum level control | Instrumentation and

2019-10-22 · Three-element drum level control is ideal when a boiler plant consists of multiple boilers and multiple feed water pumps or where the feed water has variations in pressure or flow. The independent tuning of each controller allows a very precise control of the level of the drum, independently of the steam demand and the influences of the feed water.

Boiler Safety and Role of Low Water Levels

Controlling the boiler drum level is complicated as the "water level" in a steam drum is actually a fairly unstable mixture of water and steam bubbles that shrinks and swells as the pressure changes. This is because of the fact that as the steam demand increases, the pressure in the boiler drops causing the water level to rise.
