Drum level is frequently also measured by Eye-Hye a device like a sight glass with relays to indicate whether each (separated by an inch or two) has water or notBecause the temperature of the water in the Eye-Hye is colder and more dense than the water in the drum the water in the Eye-Hye tube will be several inches lower than the level in the drum when at high temperaturesGet a Quote

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 loopThis arrangement is called Three Element Drum Level Control (3E) because the algorithm uses level BFW flow and steam flowGet a Quote
The feedwater TDS in parts per million An average value may be obtained by looking at water treatment records or a sample of feedwater may be obtained and its conductivity measured As with boiler water TDS measurement conductivity (S/cm) x 07 = TDS in parts per million (at 25°C)Get a Quote
