Boiler Steam Drum Level Control Strategies

The purpose of drum level controller is to keep the level at desired value, optimal interface level requires between steam and water within the steam drum. It is essential that the level of liquid must be low enough to assure that there is appropriate separation between steam and water and high enough to guarantee that the water exists in every steam generating tube.

Methods of Detecting Water Level in Steam Boilers | …

As it does so, the water surface area (steam release area) will decrease because, as the water level is above the centre line of the boiler, the sides of the containing shell converge. The boilermaker will have designed the boiler to ensure that the area of the normal water level (NWL) is such that steam will be released at an acceptable velocity.

Steam Boiler Water Level - YouTube

On a steam raising boiler there are three clear applications for level monitoring devices: Level control - To ensure that the right amount of water is added to the boiler at the right time. Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level.
