Analysis of operating situation of existing an hydrous sodium sulfate evaporator and the measures of improving its evaporating strength

Through the analysis of operating situation of existing evaporator of anhydrous sodium sulfate.It was pointed out the disadvantages of existing evaporator and the factors of effecting evaporating strength,such as convection heat transfer cofficient of solution in the tube and thermal resistance of scals.Thus the measures of improving the evaporating strength were put forward.
