scaling in boilers - lennte

Scaling in boilers - Lennte

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the ...

Silica is present in all natural water supplies in some form. Additionally, many foods such as, strawberries, avocados, onions, root vegetables, wheat and oats contain silica. And, it can found in nature as sand, sandstone, quartz, flint, agate or granite. Being a hard, glassy substance on its own, silica is commonly used to make glass.

Silica Monitoring TECHNICAL NOTE On Power Pla

to confirm that the maximum level of silica permissible in the boiler is not exceeded. 9 – Boiler Drum Silica build-up is monitored inside the boiler drum. The silica concentration is distributed between the water and vapour phases in a boiler. As the temperature and pressure are increased, more silica becomes present in the steam.
