Boiler Drum Level Control System
Tek-Bar 3110B Smart Differential Pressure Transmitter
Boiler Drum Level Control System is used in institutional and industrial heating plants where steady process condition, continuous type process with good feed-water pressure regulation is essential. It is also used in combination of batch and continuous type operation plant where, steam load characteristics are continuously changing and unpredictable.
When the level of the boiler steam drum is measured by differential pressure transmitter, some physical properties must be considered as following:
- At saturation, the steam drum contains a two-phase mixture of water and steam.
- The densities of water and steam vary with temperature and pressure saturation.
- The density of saturated steam above water, and water in the drum, must be considered.
