摘要： 研究了用非离子表面活性剂制备含水柴油乳状液和微乳液的条件,测定了掺水柴油在不同燃烧条件下的放热量。结果表明,在供氧充分的条件下,水的掺入对燃烧热无贡献。若在大气中燃烧,掺水柴油以喷燃方式进料,一般掺水量以10%～20%(W/W)时燃烧效率较高。若水中含有某些金属离子,掺水量达30%,仍有较高的热效率。柴油微乳液的稳定性虽比柴油乳状液好,但只要两者的含水量相同,燃烧时的放热量相同。

Abstract: The preparation of water containing diesel oil emulsion and microemulsion by using nonionic surfactants as emulsifiers was studied. The combustion heat of water-doped diesel oil was measured under different combustion conditions. The results showed that the incorporation of water in diesel oil did not improve the combustion efficiency under rich oxygen condition(in the oxygen bomb), but the calorific efficiency was improved when the diesel oil containing water was atomized directly into the combustion chamber under atmospheric condition. To get a higher combustion efficiency, the amount of water incorporated in diesel oil generally should be about 10%～20%, but it can be up to 30% in the presence of some metallic ions in water. The diesel oil microemulsion is much more stable than the emulsion containing equal content of water, but the combustion heat in both of them is all the same.

Key words: nonionic surfactant, emulsification of diesel oil, combustion efficiency
