After the material balance for any a mixing pool, the analytical solutions of concentration on the evaporatingsurface, the distillate rate and the residue rate obtained.
对每个混合池进行物料衡算，可以得到蒸发壁面上浓度的变化和轻、重馏分流量和含量解析解。

Water is part of a large cycle: it travels over land via rivers and lakes and through the oceans before evaporating \ into \ the atmosphere and eventually returning to the surface by precipitation.
Since the header on the evaporating heating surface adopts pre-separation structure, the effectiveness and speed of water-steam separation in the drum are improved.
