一、前言 目前,由于受石油化工行业深加工影响,以及石油资源的日益减少,我国目前燃料油的品质均较差,使得炉窑现有的油枪无法达到完全燃烧和节能要求,普遍存在雾化粒度大、燃烧不完全、冷炉重渣油直接点火困难,难以保证炉窑的正常温升。为此,只得增加喷油量,由于喷枪雾化不良,喷枪结焦、堵塞、磨损严重,未燃烧的油滴还直接影响到其它工艺系统设备的故障及效率。普通机械雾化喷枪和气动内混、外混喷枪以及Y型蒸汽雾化喷枪,常见的情况是,雾化性能差、燃烧不充分、易结焦,所需油压较高,造成工艺系统稳定性差等。随着科技的进步,人们通过实践证实,采用高效雾化喷嘴是 I. Introduction At present, due to the deep processing of the petrochemical industry and the declining oil resources, the current quality of fuel oil in our country is poor, which makes the existing oil guns in the kiln unable to achieve the requirements of complete combustion and energy saving. Generally, atomization Large particle size, incomplete combustion, direct ignition of heavy oil residue furnace difficult, it is difficult to ensure the normal furnace temperature rise. To this end, only increased fuel injection, spray gun due to poor atomization, spray gun coking, clogging, serious wear and tear, unburned oil droplets also directly affect the other process equipment failure and efficiency. Common mechanical atomization spray gun and pneumatic mixing, mixing spray gun and Y-type steam atomization spray gun, the common situation is poor atomization, combustion is not sufficient, easy to coke, the required high hydraulic pressure, resulting in poor stability of the process system Wait. With the progress of science and technology, people have confirmed through practice that adopting high efficiency atomizing nozzle is
