In Forced Circulation Evaporator the liquid is pumped through the tubes with high velocity. As the liquid enters the separator where the absolute pressure is slightly less than in the tube bundle, the liquid flashes to form a vapor.It is suitable for use with materials which tend to foul the heat transfer surfaces and where crystallization can occur in the evaporator.
