| 摘 要： | 在冷态模拟实验中，就交叉射流的参数对主变形率的影响进行了研究，增加交角、提高出口动量比和保持两枪之间适当的距离都有利于提高混合效果，对不同类型喷枪的煤粉燃烧率进行了热态模拟实验，发现采用交叉式氧煤双枪和双煤枪可以获得比单枪较高的燃烧率，这表明交叉射流为煤粉在风口前的燃烧提供了良好的传热和传质条件。

| Abstract: | Through a water simulation experiment, the influence of cross jet parameters on principle strain was studied. It is beneficial to the mixing effect by increasing the cross comer and momentum at outlet and keeping an appropriate distance between the two lances. The effect of different types of lances on the combustion rate of pulverized coal was researched in laboratory. The results show that the oxygen and coal double lances or the two coal double lances could obtain a higher combustion rate than any type of single lance. It is concluded that cross jet can achieve a good condition of heat and mass transfer for the combustion of pulverized coal in front of a tuyere. |
