Water Level control for boiler Agent

3-Element Boiler Feed Water Control • Strategic Automation

Feed Water Control, Level Measurement and Safety. Level Measurement and Safety. The boiler drum is where water and steam meet and separate from each other. The water level here is one of the important parameters to be measured and controlled. For the boiler to operate safely and efficiently, the water level in the drum must be kept constant.

The water level should drop sufficiently for the float to open the mercury switch and shut the boiler down. At the same time, any sediment collected in the chamber and connections will be flushed down the drain. The water level in the chamber should quickly return to normal once the valve is closed. The boiler will start up again automatically.

Oct 31, 2019 · Being an indicating controller, the controller faceplate will still show how much water is in the steam drum, but it is now the human operator's sole responsibility to move the control valve to the appropriate position to hold water level at setpoint – in manual mode the controller takes no corrective action of its own. Manual mode is useful to human operators during start-up and shut-down conditions.

US7409301B2 - Boiler water level monitoring and control

Accurate feed water control is crucial for efficient, reliable boiler operation. Too low of a water level will expose boiler tubes to overheating, possibly damaging them. Too high of a water level can cause water carryover. The Siemens Electronic Water Level Control System maintains a consistent water level that minimizes these potential concerns.

The controller then generates an output signal telling the control valve to either introduce more or less water into the boiler to maintain the steam drum water level at setpoint. As with the transmitter, the controller in this system is pneumatic, operating entirely on compressed air. This means the output of the controller is also a variable
