How is sludge and sediment removed from the gauge glass and water column?

Sludge and sediment removal from the gauge glass and water column is primarily accomplished through a blowdown procedure. Blowdown involves the intentional release of water from the boiler, which not only helps to manage pressure and maintain the correct water level but also serves to remove accumulated impurities, including sludge and sediment. This process is crucial for maintaining the efficiency and safety of the boiler system by ensuring that the gauge glass remains clear for accurate water level readings and that the water column does not become obstructed. Regular blowdown practices help to prevent the build-up of harmful materials that can affect boiler operation and performance.
