Silica Scaling in Boilers - Lenntech

Silica Scaling in Boilers - LenntechSilica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. In the analyses of various surface and ground waters, silica content range from 1 to 107 ppm.This refers to soluble silica content and not to the silica that may be present in the suspended matter.Scaling in boilers - LenntechBoiler 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 Scaling in Boilers - LenntechSilice Scaling in caldaie.

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.

Boiler water treatment - LenntechThe treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the Boiler make-up water - LenntechBoiler water quality shall be set according to the boiler pressure and type of heater. Lenntech can provide you all water treatment equipment, including chemicals. Caustic corrosion in boilers. Silica Scaling in Boilers. Filtration. A propos de Lenntech.
