许多工业炉窑,如反射式化铁炉、平炉、大型轧钢加热炉、玻璃窑、搪瓷窑等,由于工艺的要求,需要刚性好,火焰长的火焰.目前我国这些炉窑大都采用高压外混式油枪,这种油枪产生的火焰长,刚度好,对油质的要求不高,但它存在以下几个问题:(1)雾化性能差这种油枪油是从中心油管喷出,呈束状,雾化介质从油管外的环形空间喷出,油汽在管外雾化,由于油汽为同心射流,且相互的交角又小,因而混合时间长,雾化质量差,在燃
Many industrial furnaces, such as reflective iron furnace, open hearth furnace, large steel rolling furnace, glass kiln, enamel kiln, due to process requirements, require rigid, flame long flame. At present, most of these kilns in China using high pressure external mixing The type of oil gun, the flame produced by this gun long, good stiffness, less demanding on the oil, but it has the following problems: (1) poor atomization oil gun oil is discharged from the center of the tubing , In the shape of a bundle, the atomization medium is ejected from the annular space outside the oil pipe, and the oil vapor is atomized outside the pipe. Since the oil vapor is a concentric jet and the intersecting angle is small, the mixing time is long and the atomization quality is poor. Burning
