design of single loop control scheme for boiler export steam pressure

The Analysis and Design of Improved Control Systems for ...

Aug 01 1981 · In a TFB scheme boiler pressure variations are used to control the position of the turbine governor valve and Dower demand variations are injected primarily to the boiler firing rate. A TFB system can readily be studied using the model Analysis and Design of stated previously in the System Transfer Function Model section.

What you don't know about Steam Boiler Drum Level Control ...

This creates two control loops in a controller the level control loop and the feed water control loop. The principle of the three-element configuration is to control the mass balance of the steam drum. If steam is removed from the boiler circuit the steam loss must be replaced with an equal mass of feed water.
