摘　　要：乳化重油的分散相 (水 )微粒大小对重油掺水乳化燃烧技术的应用效果有很大影响。本人在过去实验的基础上 ,用光学反射显微镜法对磁场作用下掺水乳化重油中分散相 (水 )的分散度进行了测定 ,研究了乳化重油的分散度与磁场强度、温度以及流速之间的关系 ,实验结果表明 :磁化后有利于乳化重油的微细化 ,且效果比较显著 ;温度的升高有利于分散相 (水 )的微细化 ,兼顾能耗和燃油的发泡、沸腾现象 ,以及磁化后温度的升高对分散度的影响减少 ,有一个合理的温度范围 ;磁化后分散度与流速的关系呈峰值关系 ,本实验中流速较佳值为 8m s ;磁场强度的增大也有利于微细化 ,磁场强度太高或太低均不会取得太好的处理效果 ,在 10 0 0GS～ 140The disperse phase (water) droplet size of emulsified heavy oil(EHO) has a significant effect on the combustion of water in heavy oil emulsion By means of microscope, the disperse degree of disperse phase in EHO is measured before/after magnetization in various experimental conditions, and the relationships of the disperse degree with the magnetic strength, temperature and the liquid velocity were studied The following results are obtained: magnetic treatment has a significant effect on disperse degree of EHO, namely droplet size of disperse phase; the increase of temperature favors the disperse effect of water in EHO; in view of energy consumption and the influence of temperature on disperse degree, there is a rational temperature range; the disperse degree (or droplet size) has a peak relation with liquid velocity of which the better value is 8?m/s, increasing the magnetic strength will also lead to a better disperse effect, and a good magnetization effect will be obtained when magnetic strength varies in the range from 1000 to 1?400?GS
