Abstract
The distribution of effective temperature differences in the flash evaporator was investigated by examining the data on the operation of the flash evaporator, and this study proved to be useful for analying this process. Also, it was found that the elevation of the boiling point in the process of desalting sea-water by flash evaporation method could be expressed by the following formula:
dt=C1.173(0.1120±180×10-3t)
50<t<100°C 5<C<11wt%
Non-equilibrium temperature differences were calculated by the following formula:
Δt=1.056Re-0.469Pr-0.667t-1.636
It was pointed out that the overall heat transfer coefficient of 4,500 (Kcal/m2hr°C) could be attained easily.
