乳化重油作为节约燃料和降低有害排放量的有效措施,在国外得到广泛应用。法国石油公司早在1965年就用乳化搅拌装置在工业炉上试用,到1979年已在2000多台炉子上取得成效;在日本,燃烧乳化重油还意味着安全和降低污染,经十多年的研究已进入实用阶段。据国外报道乳化重油的节能幅度约为2～30%,降低污染幅度分别为 NOx:20～50%、SOx:50%左右、烟尘:20～90%。因添加剂价格贵,故燃烧乳化重油大多采用搅拌机或电超声装置等进行乳化,只有在输送管道较长时才使用添加剂。国内从60年代开始就开展这方面的试验研究工作,用乳化装置(搅拌器、电超声、弹片哨等)进行乳化,掺水量一般不超过10%,输
As an effective measure to save fuel and reduce harmful emissions, emulsified heavy oil has been widely used abroad. As early as 1965, French oil companies experimented on industrial furnaces with emulsifying agitators and achieved results on more than 2,000 stoves by 1979; in Japan, the burning of emulsified heavy oil also meant safety and pollution reduction. After more than a decade Research has entered a practical stage. According to foreign reports, the energy-saving rate of emulsified heavy oil is about 2 to 30%, and the reduction of pollution is respectively 20 to 50% of NOx, 50% of SOx and 20 to 90% of dust. Due to the expensive additives, the majority of emulsified heavy oils are emulsified with a mixer or electric ultrasonic device, and the additives are used only when the delivery pipelines are long. Domestic 60 years from the beginning to carry out experimental research in this area, the emulsification device (stirrer, electric ultrasound, shrapnel whistle, etc.) for emulsification, water content is generally not more than 10%, lose
