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

How Scale Impacts Boiler Performance | Goodway

2020-5-7 · Scale builds up over a longer period of time and also contributes to boiler inefficiency. Heat loss of 8% and increased fuel consumption of 2% will result from only 1/32" (0.8mm) of scale in the boiler tubes. In a water tube boiler, water runs through tubes that are surrounded by the heating source. Because the water is heated to very high

water maintenance essential to prevent boiler scaling

Water Maintenance Essential to Prevent Boiler Scaling

When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.
