Heating Area: Determine the evaporator heating area is a reference material balance, heat balance, heat transfer calculation and post-process such as the use of form factors considered in making a decision. From the use of multi-effect evaporator to distinguish it can be divided into: ordinary multi-effect evaporation system, forced circulation multi-effect evaporator. Forced circulation evaporator is evaporated by the outer loop based on more than one additional external circulation pump. Generally speaking, the energy consumption with heat pump double-effect evaporation system with almost three-effect evaporation system, it can increase the flow of materials within the evaporator tube to improve heat transfer effect, increasing evaporation intensity. 1. Select the number of effects: the first major increase in the value of black liquor and consider how much evaporator manufacturers, and device size of the amount to be treated, as well as the boiling point of the material to be evaporated. If the processing capacity we should adopt more efficient operation; the more the number of its efficiency, the consumption of steam, the smaller model with black liquor evaporator, the higher the investment in the device; boiling point elevations will be great, to be effective temperature difference is small the number of effect used should be reduced.
