Controlling Boiler Level When Operating Conditions Chan

Maintaining the right water level in the drum is critical. If the water level is too high, it can be carried into the steam line, and if it makes it all the way to the main turbine, it can damage blades. If the water level is too low, parts of the boiler may go dry and overheat.

Boiler Water Level Controller: Components & Workin

The main purpose of the water level controller is to bring the drum up to level at boiler start-up and maintain the level at all time. A sudden decrease in this level may uncover boiler tubes, causing them to become overheated and damaged.

Methods of Detecting Water Level in Steam Boilers | Spir

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.
