Sugar leakage detection in boiler feedwater

Sugar leakage detection in boiler feedwater

All sugar mills use steam from the boiler as a source of energy, for example, in the evaporators or during crystallization. It is common practice and economically viable in the mills to utilize the vapor from one or several effects of the evaporators to the clarifiers or settling tanks. As the steam releases energy, steam condensates to distilled water that can be used as feed to the boilers. However, condensates might get contaminated making them unfit for use if juice leaks or overflows into the equipment. Feedwater with excessive amounts of sugar, above 200 ppm, can be extremely damaging for boilers causing a variety of problems including foaming, fouling, corrosion, and in the worst case lead to an unplanned shutdown. Accurate sugar leakage detection is crucial in mills to allow rapid response prior to damage to equipment occurs and to prevent financial losses.
