EVAPORATOR AND FRESH WATER GENERATOR: Most Frequently Asked Questions on Fresh Water Generator

By -
    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 c...

                          PULSE SYSTEM  OF LUBRICATION  In the shipping industry, two giants –MAN AND Wartsila  have introduced a remarkable technology for modern electronically controlled marine engines. Known as Alpha and Pulse lubrication systems, this new technology is one-of-its-kind. What is Pulse Lubrication System? A pulse lubrication system is an electronically controlled cylinder oil lubrication system for Wartsila engines, wherein metered quantity of cylinder oil is injected in to the liner, depending on the engine load. This ensures that accurate amount of cylinder oil is delivered inside the liner at the correct set-time for that particular engine load Construction and Working of Pulse Lubrication System There are normally eight quills attached to the cylinder liner in a single row, which gets the oil supply from the electronically controlled dosage pump The oil is supplied to t...
