Three Element Drum Level Control | CrossCo

2019-5-29 · How can steam drum level be controlled to maximize both stability and responsiveness? The best method is to feed forward (FF) the steam flow to the level PID loop and cascade the output of that loop to the setpoint of a boiler feedwater (BFW) flow loop. This arrangement is called "Three Element Drum Level Control" (3E) because the algorithm uses level, BFW flow, and steam flow.

Traditional Versus New Technology Boiler Drum

The art and science of boiler drum water level measurement has long been the source of questionable results. A low-tech examination of the boiler drum reveals where the drum level has been controlling there is a water mark inside the drum. The problem is obvious; the mark in the drum and that in the control system do not agree.

3 Element control for boiler drum

Hence, poor boiler circulation usually translates in long boiler drum level deadtime and high shrink-swell effect. If you take any boiler (say 70,000 kpph +) and increase the firing rate by 20%, the boiler drum level will go up IF YOU MATCH THE FEEDWATER FLOW WITH THE STEAM FLOW. If you increase the firing by a larger amount, you might trip.

Abstract: In order to improve the dynamic stability of level control system in the steam drum of boiler, a fault diagnosis approach is proposed by using IDEF method, which can analyze the control system structure by the IDEF model. When the faults occur, the possible causes of fault can quickly be identified by using the model.
