Show by an equation one cause of boiler scale
WebBoiler 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 … WebSep 8, 2024 · To calculate boiler efficiency using this method, divide a boiler’s total energy output by the boiler’s total energy input, multiplied by a hundred. E= [Q \frac { (H-h)} {q}\times GCV]\times 100 where, Q= Quantity of generated steam (kg/hr) H= Enthalpy of the steam phase (Kcal/kg) h= Enthalpy of the water phase (kcal/kg)
