Determination of Optimum Surface Distribution in Triple-Effect Evaporator

Abstract:

Subjected to fixed total heat transfer surface area, the distribution of surface in multiple-effect evaporator affects the performance of the evaporator. Previous studies have been concerned with optimization of surface distribution with the assumption that no fouling occurs. The present study considers a more realistic case when the last-effect vessel is subjected to fouling. It is shown that, in order to consume the minimum steam exergy to produce a given amount of evaporation, the area of the last-effect vessel must be increased as the rate of fouling increases.
