大气污染是近年来环保治理的重点。因燃煤工业窑炉烟气中有NO--x, NO--x是一种主要的大气污染物，它在强光作用下会与碳氢化合物发生反应行成有毒气体，这种气体排放到空气中就会行成酸雨，严重危害生态环境。因此，在工业炉排气前要求对有毒气体进行前处理。目前，氨还原法脱硝因其工艺简单，投资成本低，成为主要的烟气脱硝法。氨气脱硝方法主要工作原理是：在压缩空气的作用下，将还原剂通过喷枪气体和液体入口在枪体内碰撞产生雾化颗粒然后喷到炉窑高温烟气中，还原剂中的氨和烟气中的氮氧化物发生化学反应，生成烟气和水，脱出烟气中的氮氧化物。
斐卓Feizhuo脱硝专用喷枪解决了普通清洗或降温喷枪气液能量交换不充分，雾化效果不好，还原剂雾化液滴动能不高，射程短，不能有效的将还原剂喷到预定位置，脱硝效率低，氨逃逸效率高等问题，是一款专门适用于工业炉窑的脱硝专用喷枪。
