Dan Holohan: Sludge, scale and bouncing boilers | 2021-05

May 05, 2021 · Clogging up heating surfaces is sort of like having all the traffic lights in your town turn red at the same time, and then stay red. Most movement just stops. In the case of boiler sludge and scale, that movement is heat. It's trying to get from the fire, through the metal, and then onto the conveyor belt of flowing water but sludge and scale can block the way.

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
