EVAPORATOR AND FRESH WATER GENERATOR: Most Frequently Asked Questions on Fresh Water Generator
Most Frequently Asked Questions on Fresh Water Generator (1) Explain the Freshwater generator working principle. Ans:- The basic principle of all low-pressure freshwater generators is that the boiling point of water can be reduced by reducing the pressure of the atmosphere surrounding it. By maintaining a low pressure, water can be boiled at low temperatures say 50 degrees Celsius. The source of heat for the freshwater generator could be waste heat rejected by main engine jacket cooling water. (2) How to Minimize Scale Formation in Shell & Tube type Fresh water generator? Ans;- Scale formation in the freshwater generator can be controlled and minimized by continuous chemical treatment. Polysulphate compounds (like sodium polysulphate) with anti-foam are preferred by marine engineers and are extensively used on ships. Their trade name is different, like: Vaptreat (by MONITOR) Ameroyal (by DREW CHEMICALS) These chemicals minimize calcium carbonate scale format
