FORCED CIRCULATION EVAPORATOR PLANT
Forced circulation evaporator is used if boiling of the product on the heating surfaces is to be avoided due to the fouling characteristics of the product, or to avoid crystallization. The flow velocity in tubes must be high and high capacity pumps are required. In Forced circulation evaporator plant, the solution to be evaporated is circulated by circulation pump through the heat exchanger tubes with high velocity from bottom to the top. The vaporization takes place in the vapour head, where the vapour and liquor are separated by gravity and / or by centrifugal force.
Forced circulation Evaporators are available for capacities ranging from 100kg/hr to 15,000kg/hr.
