随着石油工业的技术进步,炼油厂深加工水平的提高,重油的粘度已越来越高,它使得燃油工业炉烧嘴的雾化质量越来越差,以致造成燃烧不完全,能耗增加,环境污染,甚至正常生产都难以进行。因此,降低重油的使用粘度已成为提高工业炉燃烧效率和维持正常生产的关键。目前国内重油的加热办法主要有蒸汽加热和电加热两种。蒸汽加热只能将重油加热到90℃,此时其恩氏粘度为12～15°E.而烧嘴达到设计雾化质量时所要求的重油粘度是5°E.电加热虽然能够将重油加热到
With the technological progress of petroleum industry and the improvement of deep processing level of refineries, the viscosity of heavy oil has been getting higher and higher. As a result, the atomization quality of the burners in fuel industrial furnaces is getting worse and worse, resulting in incomplete combustion and increased energy consumption, Environmental pollution, even normal production are difficult to carry out. Therefore, reducing the use of heavy oil viscosity has become the key to improve the combustion efficiency of industrial furnaces and to maintain normal production. At present, the heating methods of heavy oil in China mainly include steam heating and electric heating. Steam heating can only heat the heavy oil to 90 ° C, at which time its Engler viscosity is 12 to 15 ° E. The burner viscosity required for heavy oil at the design atomization is 5 ° E. Although electric heating can heat heavy oil To
