本文对二元液体混合物的沸腾传热机理进行了探讨。由于加热表面性质对二元混合物佛 腾给热系数的影响很大，所以用机械方法在加热表面上，做成一些凹孔作为固定的汽化中 心，在此种表面上，可保证在一定的热负荷范围以内，汽化中心数与液体种类、混合物的组 成和过热度三者均无关。选择了乙醇──水，正丙醇──水，苯──甲苯和乙醇──苯四种 二元系统进行沸腾实验并与普通表面上的实验结果作了比较。
In this paper, the boiling heat transfer mechanism of binary liquid mixture is discussed. Since the heating surface properties have a great influence on the fouling coefficient of heat of the binary mixture, some concave holes are mechanically formed on the heating surface as a fixed vaporization center, and on such a surface, it is guaranteed that a certain amount of heat Within the load range, the number of vaporization centers has nothing to do with the type of liquid, the composition of the mixture and the degree of superheat. Four kinds of binary systems of ethanol - water, n - propanol - water, benzene - toluene and ethanol - benzene were selected for boiling experiment and compared with the experimental results on common surface.
