Water for the Boiler - beta.spiraxsarco.com

Water-tube boiler plant. Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate.

Scaling in boilers - Lenntech

Causes, and prevention of scaling in boilers, type of scaling. 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.

2019-7-11·When a boiler generates steam impurities in the feed water will concentrate in the boiler water. When the concentration of impurities becomes higher, foam is generated and the volume of the boiling water starts to increase. As a result - more and more low quality wet steam will be generated.
