steam relieving area

When the evaporation area in multi stage film fall evaporator has been determined, in practical application, the heat in each stage and the medium liquid evaporation will reach the balance automatically.

多效降膜式蒸发器蒸发面积一经确定后,在实际应用过程中各效热量分配及料液蒸发是一个自动要求达到平衡的过程,理论上总蒸发面积确定后,各效蒸发面积可以进行一定量的调整分配,这样调整分配可以消除结焦,就此加以阐述。

The relation between oil evaporation surface and evaporation loss is studied, and oil evaporation surface is incorporated into Varevskii-Chernikin Formula, this make it find a better application in the calculation of evaporation loss of oil with surface cover; Various methods taken in China and abroad for reducing the evaporation loss of light fuel oil are summarized and evaluated.

研究了油品蒸发表面积与蒸发损耗之间的关系,并将油品蒸发表面积因子引入瓦廖夫斯基—契尔尼金公式,使之能更好的应用于带有表面覆盖层的油品蒸发损耗的计算;对国内外降低轻质燃料油的蒸发表面积所采取的各种方法进行了综述和评价。
