Gas Flow in Control Valves | Valin

Jan 05, 2015 · The principle difference between the nature of the flow of gas and the flow of liquid through control valves is that liquids are incompressible and gasses are compressible. When the pressure of a liquid changes, the volume and density, ρ, remain unchanged, while on the other hand, pressure changes in a gas result in both volume and density change.

Boiler Firing Controls Functional Specification

However, a detuned level controller can let the level get away at times. This is especially true at low load. In addition, the steam flow can be erratic at low load. Therefore, the level controller automatically switches between three-element and single-element control (level controller output direct to valve), depending on the load.

Steam Boiler Water Level Control | The Industrial Steam

This means the control system must add feedwater to the boiler at a much greater flow rate in order to maintain the steam drum water level at setpoint. In this situation we would expect to see the control valve much closer to being fully-open as the control system "works harder" to maintain a constant water level in the steam drum.
