Abstract
Global resources of freshwater are scarce, unevenly distributed and, in many cases, may require some form of treatment and handing. There are many types of desalination systems multi-effect desalination(MED), multi-stage flash desalination(MSF), reverse osmosis desalination(RO) and electro-dialysis(ED). Each type of desalination is limited and different according to surroundings, environments and conditions. With advanced technologies in scale control and material selection, Multi-effect is now playing a major role in seawater desalination systems. Multi-effect is inherently superior in economy, low specific electricity consumption, and embraces the possibilities of using lower grade materials to a better effect.

In the present paper, safe operating conditions of the duel effect desalination system were examined by varying the temperatures of the hot water and the feed water. The duel effect desalination system was made by modifying a fresh water generator used in the ship. Pressures and temperatures were kept at a steady state. The effect of the feed water and hot water temperatures on fresh water generating rates were explained. The overall heat transfer rates of heat exchangers were reduced from raw data and the effect of inlet conditions on the overall heat transfer rates were described.
