Effects Of The Seawater In Steam Boiler

Marine Boilers - Marine Engineering Knowledge Part 1

Boiler blow down is made to reduce the density of salt and to remove the dissolved and suspended solids, also the floating solid impurities in the boiler system. If there are not removed from the boiler water system, foaming, priming, corrosion will occur in the boiler steam space and feed water system. See 'Boiler Blow Down'.

Scaling in boilers - Lenntech

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
