Sludge and scale
Webb19 maj 2024 · 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. So the boiler just keeps getting hotter as the building gets colder, and that's not good for either one. Webb15 feb. 2024 · Primary sludge contains more fat and fibre (6–35 and 18–25% DS, respectively), but less protein (16–30% DS), compared to surplus activated sludge (SAS) (1–12, ≤10 and 30–60% DS, respectively), and the reported carbohydrate contents in both sludge types are relatively similar (18–28% DS).
