Multi-effect evaporation systems using steam jet pumps
Thread Content
I would like to ask everyone: in multi-effect evaporation, a steam jet pump (heat pump) is used in the first effect, which increases the amount of vapor supplied to that effect. My question is: since the amount of vapor supplied to the second effect decreases as a result, how will the evaporation efficiency of the second effect be affected? Also, is the heat exchange area of the first effect the same as that of the other effects? Thank you
Generally speaking, as the amount of steam entering the second effect decreases, the evaporation efficiency of the second effect will decline. The heat exchange area of the first effect should be calculated based on the amount of evaporation (heat load, heat transfer coefficient, temperature difference); it may be the same as that in other effects or it may differ
