喷嘴广泛应用于湿法脱硫、除尘等设备中，雾化液滴中位粒径D50是评价喷嘴雾化的重要参数。对孔径分别为1.44μm和0.46μm的喷嘴进行不同压力、距离雾化实验，并采用不确定度的评价方法评估了雾化液滴D50值的不确定度。实验和评价结果表明：尽管喷嘴使用条件改变，雾化液滴D50值存在着较大的差别，但相同条件下雾化液滴的D50偏差不大，合成不确定度值小于5.00μm。进一步说明雾化液滴D50值是由喷嘴结构所决定，用D50指导喷嘴选择是可靠的。

Nozzle is widely applied in the devices of wet desulphurization,dust removal and others, the D50 of the atomized droplets is the key parameter to evaluate the nozzle. Atomization experiments of different pressure and distance for the nozzle with the apertures of 1. 44μm and 0. 46μm were car?ried on,and the uncertainty values of the D50 of the atomized droplets are calculated with uncertain?ty evaluation method. The experiment and evaluation results indicate,the D50 value of the atomized droplets changes a lot with the change of atomized conditions,but the deviation of the D50 values in the same conditions is small with the maximum value of measure of uncertainty being 5μm. And the further conclusion is that the D50 of the atomized droplets is determined by the structure of nozzle, and it is reliable to guide the selection of nozzle with D50.
